AB  - In this paper, we have systematically studied the structural, morphological, and optical properties of Ni-doped TiO2, synthesized via a simple, cost-effective electrospinning method followed by calcination at 500 C. The nanofibers with a core-shell structure were relatively homogeneous, smooth and randomly oriented, and there were no significant differences in fiber diameters due to Ni2+ content. Core loss mapping using electron energy loss spectroscopy confirmed an even distribution of titanium and relatively uniform nickel in the fibers. It was found that doping with 0.5 mol.% Ni2+ decreased the rutile content, while doping with 1 mol.% Ni2+ resulted in a pure anatase phase with a significantly increased specific surface area (36.6 m2/g). Further increase in Ni2+ content (3-10 mol.%) not only prolonged the response of TiO2 nanofibers to visible light, but also increased the specific surface area (49.5 m2/g), decreased crystallite size (7 nm), and increased rutile content in TiO2 (33 wt.%). Photoluminescence analysis revealed that doping TiO2 with different amounts of Ni2+ leads to a gradual decrease of emission spectra intensity and red shift in the maxima positions. The XPS results confirmed that as the Ni2+ content enlarged, the Ti2+ and Ti3+ content increased significantly, effectively promoting the formation of oxygen vacancies. Raman analysis showed that an increase in nickel content (3-5 mol.%) led to a decrease and shift in peak intensity due to Ti3+ formation and also the possible presence of NiTiO3 phases. HRTEM analysis showed that Ni was doped into the substitution sites of both the anatase and rutile TiO2 lattice but had a stronger influence on the distortion of the anatase phase. The photocatalytic activity of Ni-doped TiO2 nanofibers was explored by analyzing the degradation of an antibiotic, oxytetracycline, monitored in laboratory conditions under visible light irradiation. After 60 minutes of irradiation, the degradation  of OTC with 1Ni-TiO2 reached 76.4% and with 10Ni-TiO2 70.5%.

AB  - Mung bean (Vigna radiata L.) is a leguminous plant cultivated mainly in south-east Asia and used as an ingredient in local cuisine. Its principal nutritional value is contained in its constituents such as starch, proteins, (poly)phenols, and natural antioxidants. Fluorescence spectroscopy is increasingly used as a method of choice for food analysis; due to the presence of different fluorophores originating from aromatic amino acids and secondary metabolites, it is useful for proteins and phenolics detection. In this study, the total protein and phenolic contents of mung bean seed extracts were determined using the Bradford method and Folin–Ciocalteu (FC) reagent, respectively. Antioxidant activity was determined using DPPH (2,2-Diphenyl-1-picrylhydrazyl) assay. Fluorescence spectra were recorded for a series of excitation-emission wavelengths. Further, we used the multivariate analysis on the recorded excitation-emission fluorescence matrix of the studied samples. The results showed the presence of three different fluorescence components, with the position of the emission maximum corresponding to the fluorophore of proteins (component 1 with excitation/emission peak maxima at Ex 290/Em 345 nm) and phenolics (component 2 - Ex 295/Em 395 nm and component 3 - Ex 350/Em 450 nm). This fluorescence-based method could be a useful approach for estimating the nutrient properties of leguminous food.

AB  - Food is a complex matrix of proteins, fats, minerals, vitamins, and other components. Various analytical methods are currently used for food testing. However, most of the used methods require sample preprocessing and expensive chemicals. New analytical methods are needed for quick and economic measurement of food quality and safety. Fluorescence spectroscopy is a simple and quick method to measure food quality, without sample preprocessing. This technique has been developed for food samples due to the application of a front-face measuring setup. Fluorescent compounds–fluorophores in the food samples are highly sensitive to their environment. Information about molecular structure and changes in food samples is obtained by the measurement of excitation–emission matrices of the endogenous fluorophores and by applying multivariate chemometric tools. Synchronous fluorescence spectroscopy is an advantageous screening mode used in food analysis. The fluorescent markers in food are amino acids tryptophan and tyrosine; the structural proteins collagen and elastin; the enzymes and co-enzymes NADH and FAD; vitamins; lipids; porphyrins; and mycotoxins in certain food types. The review provides information on the principles of the fluorescence measurements of food samples and the advantages of this method over the others. An analysis of the fluorescence spectroscopy applications in screening the various food types is provided.

AB  - Honey bees have a very important role in pollinating plants, in addition to honey production. Bee
diseases are one of the reasons of a significant decrease in bee colonies in the world in recent years. Honey samples originating from hives with different infestations with N. ceranae were analyzed. Total phenolic content and total protein content were determined by the Folin-Ciocalteu assay and the Bradford assay, respectively. Fluorescence spectroscopy combined with PARAFAC was used to determine the spectral components originating from proteins (PFSC1) and phenolics (PFSC2) in honey samples, and their ratios were calculated. Phenols and proteins content in the honey samples, obtained by spectrophotometric quantification, decreases with increasing infestation levels in the respective hives infected with N. ceranae. A negative correlation was obtained for the ratio of PARAFAC components PFSC2/PFSC1 and the level of infestation with N. ceranae in honey samples. These results indicate that fluorescence spectroscopy combined with PARAFAC could be used as an optical tool for non-invasive and rapid screening of honey to estimate bee health status.

AB  - In this work, titanium dioxide (TiO2) nanofibers doped with 0.5–5 mol% 
zirconium ions (Zr4+) were synthesized by combining the sol-gel process and 
electrospinning method, and calcined at 500 °C. The morphological, structural and 
optical properties of pure and Zr-doped TiO2 nanofibers were investigated. According to 
the XRD and FTIR analyses, the addition of Zr as a dopant suppressed the 
transformation of anatase to rutile phase. Scanning electron microscopy showed that all 
fibers were smooth, fragile and randomly oriented after the calcination process. HRTEM 
analysis revealed that Zr4+ ions were incorporated at the substitutional sites in the anatase 
TiO2 crystalline lattice. The photocatalytic efficiency for degradation of methylene blue 
(MB) was examined for both pure and Zr-doped TiO2 samples. Nanofibers doped with 
1% of Zr4+ ions have shown the highest photocatalytic activity of 98%, wich can be 
explained by considering lower PL intensity in the PL spectrum of this sample, 
indicating suppressed electron-hole recombination.

AB  - Pure, samarium (Sm3+) and zirconium (Zr4+) doped titanium dioxide (TiO2) 
nanofibers were synthesized using the electrospinning method followed by 
calcination at 500 °C for 1 h. The structure, morphology and optical properties of the 
obtained nanofibers were investigated as a function of different Sm3+ and Zr4+ 
contents (0.5–5 mol%). XRD and FTIR analysis showed that addition of Sm or Zr 
suppressed the transformation of anatase to rutile. After calcination all fibers were 
smooth, fragile and randomly oriented. HRTEM analysis revealed that doping with 
Sm didn’t affect the TiO2 crystal lattice whilst Zr4+ ions replaced the substitutional 
sites in the anatase crystalline lattice. The effects of Sm3+ and Zr4+-dopant content 
and different doses of photocatalyst on the photodegradation of methylene blue 
(MB) were monitored under UV-light illumination. TiO2:0.5%Sm3+ and 
TiO2:1.0%Zr4+ nanofibers have shown the highest photocatalytic activity of 97% 
and 98% due to red shifting of the band gap towards visible light in the case of Sm 
and suppressed electron-hole recombination shown in recorded PL spectra in the 
case of Zr.

AB  - Green synthesis is a more sustainable option using renewable biomass such as plants as
reducing or stabilizing agents compared to toxic chemical compounds. These biological
substances also behave as capping agents, which control the size and shape of the
nanoparticles. In this work, ZnO nanoparticles (NPs) have been prepared via a simple, low
cost and ecofriendly method using citrus fruit peel and extracts as biological reducing agents.
Zinc nitrate and zinc acetate were used as a source of zinc ions.XRD analysis revealed the
formation of a ZnO wurtzite phase without impurities. Synthesized ZnO NPs with an average
electronic band gap ∼3 eV were obtained and found to have round-like, hexagonal-like or
needle-like structures depending on precursor type. EDS analysis showed a homogeoneous
distribution in Zn and O elements, attributed to single-phase ZnO constituents. Antibacterial
and antioxidant activities of synthesized NPs were evaluated. Obtained results showed that
ZnO synthesized from nitrate precursors are more effective in inhibiting growth of
Salmonella and Staphylococcus Aureus. Antioxidant activity of ZnO NPs determined using
CUPRAC and ABTS assays showed higher activity of ZnO obtained using nitrate precursors.
The maximum scavenging activity of 90% was observed at the concentration of 10 mg/ml

AB  - In nature, woody substrates are usually degraded by entire communities of microorganisms, which are nowadays jeopardised by anthropogenic influence, making it important to define the functional specificity of every species. Two strains of autochthonous fungi from Serbian lowland forests (Pleurotus ostreatus Ser1 and Cyclocybe aegerita Ser1) have been investigated for their ability to degrade lignin substrates [oak sawdust, oak isolated cell walls, and synthetic dehydrogenative polymer (DHP)]. Measuring the activities of the enzymes involved in lignin degradation was coupled with detecting the HPLC profile of the phenolics in the fungal growth media, and the lignin loss. While Pleurotus ostreatus Ser1 appeared highly effective within a very short time span, Cyclocybe aegerita Ser1 failed to degrade lignin. This situation was supported by very high enzyme activities and the low presence of phenolics in the media of Pleurotus ostreatus Ser1, compared to very low enzyme activity and the high presence of phenolics in the media with Cyclocybe aegerita Ser1.

AB  - Environmental safety may be compromised by the presence of hazardous chemical compounds, such as bisphenol A (BPA), which is commonly used in the production of certain types of plastics. BPA is an emerging organic contaminant that could be found in many matrices, such as drinking water, due to anthropogenic activities. Within this study, we used fluorescence spectroscopy to analyse the photoluminescent characteristics of BPA in various solutions and drinking water. The emission spectra of BPA in various solvents are recorded from 280 nm to 380 nm, after excitation wavelength at 230 nm. These results imply that the fluorescence approach can be used for rapid detection and estimation of the level of BPA in water samples and, hence, for non-invasive monitoring of BPA in drinking water is an important concern for public health and environmental protection.

AB  - Environmental occurrence of the pathogenic fungus Aspergillus flavus (A. flavus) has hazardous
effects on the health status of plants, humans, and animals. It is important to explore novel antifungal agents to control the growth of this fungus. In this study, we aimed to evaluate the antifungal contact activity of two different types of carbon dots (CDS) nanomaterials; the one was coated with vitamin B12
(CDS@VB12) and the other was obtained from folic acid (FA@CDs). We used fluorescence
spectroscopy to obtain their fluorescence fingerprinting profile. The CDs were pipetted on the PDA
medium with sterilised filter paper placed in the center of the Petri dish. Then, pure A. flavus cultures were subcultured on PDA and incubated at 25°C for 7 days, and the diameters of mycelium growth were daily evaluated. The percentage of inhibition by CDS@VB12 ranged from 38.09% to 60.9% and from 46.03% to 71.39% for the amounts of 30 μl and 50 μl, respectively. On the other hand, FA@CDs did not show any inhibitory effect on the first day, and after that more progressive growth of A. flavus was noticed. The obtained results showed that CDS@VB12 could be considered as a potential new antifungal material against toxic and pathogenic A. flavus.

AB  - Pollen monitoring have become data-intensive in recent years as real-time detectors are deployed
to classify airborne pollen grains. Machine learning models with a focus on deep learning, have
an essential role in the pollen classifcation task. Within this study we developed an explainable
framework to unveil a deep learning model for pollen classifcation. Model works on data coming
from single particle detector (Rapid-E) that records for each particle optical fngerprint with scattered
light and laser induced fuorescence. Morphological properties of a particle are sensed with the
light scattering process, while chemical properties are encoded with fuorescence spectrum and
fuorescence lifetime induced by high-resolution laser. By utilizing these three data modalities,
scattering, spectrum, and lifetime, deep learning-based models with millions of parameters are
learned to distinguish diferent pollen classes, but a proper understanding of such a black-box model
decisions demands additional methods to employ. Our study provides the frst results of applied
explainable artifcial intelligence (xAI) methodology on the pollen classifcation model. Extracted
knowledge on the important features that attribute to the predicting particular pollen classes is
further examined from the perspective of domain knowledge and compared to available reference
data on pollen sizes, shape, and laboratory spectrofuorometer measurements.

abstract = "Pollen monitoring have become data-intensive in recent years as real-time detectors are deployed
to classify airborne pollen grains. Machine learning models with a focus on deep learning, have
an essential role in the pollen classifcation task. Within this study we developed an explainable
framework to unveil a deep learning model for pollen classifcation. Model works on data coming
from single particle detector (Rapid-E) that records for each particle optical fngerprint with scattered
light and laser induced fuorescence. Morphological properties of a particle are sensed with the
light scattering process, while chemical properties are encoded with fuorescence spectrum and
fuorescence lifetime induced by high-resolution laser. By utilizing these three data modalities,
scattering, spectrum, and lifetime, deep learning-based models with millions of parameters are
learned to distinguish diferent pollen classes, but a proper understanding of such a black-box model
decisions demands additional methods to employ. Our study provides the frst results of applied
explainable artifcial intelligence (xAI) methodology on the pollen classifcation model. Extracted
knowledge on the important features that attribute to the predicting particular pollen classes is
further examined from the perspective of domain knowledge and compared to available reference
data on pollen sizes, shape, and laboratory spectrofuorometer measurements.",

AB  - Pure and samarium (Sm3+) - or zirconium (Zr4+)-doped TiO2 nanofibers were synthesized by  electro- 
spinning method followed by calcination at 500 °C for 1 h. As-spun fibers were smooth, straight and 
continuous, whilst EDS analysis confirmed the fiber composition and incorporation  of  dopants  in  
the  fibers. Doping with Sm3+ and Zr4+ greatly inhibited the phase transformation of anatase to 
rutile, by surrounding of Sm3+ ions through formation of Ti-O-Sm bonds  and  by  replacement  of  
Ti4+  ions  with  larger Zr4+ ions. This was confirmed by HRTEM and SAED analysis. The size of 
nanofibers was determined to be 133 nm, 175 nm and 155 nm for pure, (0.5%)Sm3+:TiO2 and 
(1%)Zr4+:TiO2, respectively. After  cal- cination, TiO2 crystal lattice with interplanar spacing of 
0.353 nm of (101) crystal  plane  was not  significantly disturbed by Sm doping whilst  crystal  
lattice  spacing  of  0.357  nm  of  (101)  planes  of anatase  phase  in  case  TiO2:1.0%Zr4+,  
significantly  differs  from  the  value  of  pure  TiO2   (0.352  nm),  thus implying that Zr was 
doped into substitutional  sites  of  the  TiO2  lattice.  The  indirect  band  gaps  were 
calculated to be in the range  3.07–3.24  eV.  TiO2:0.5%Sm3+ and  TiO2:1.0%Zr4+ exhibited  higher  
specific surface area, of 47.1  and 59.4 m2/g, respectively, than pure TiO2  fibers (19.7 m2/g). 
Effects of Sm3+ and Zr4+ dopant content on the photodegradation efficiency of methylene blue (MB) 
were studied. TiO2:0.5%Sm3+ and TiO2:1.0%Zr4+ nanofibers have shown  the  highest  photocatalytic  
activity  of  97%  and 98%  with  constant  rates  0.01768  min−1  and  0.01939  min−1,

AB  - Nanometric scale size oscillations seem to be a fundamental feature of all living organisms on Earth. Their detection usually requires complex and very sensitive devices. However, some recent studies demonstrated that very simple optical microscopes and dedicated image processing software can also fulfill this task. This novel technique, termed as optical nanomotion detection (ONMD), was recently successfully used on yeast cells to conduct rapid antifungal sensitivity tests. In this study, we demonstrate that the ONMD method can monitor motile sub-cellular organelles, such as mitochondria. Here, mitochondrial isolates (from HEK 293 T and Jurkat cells) undergo predictable motility when viewed by ONMD and triggered by mitochondrial toxins, citric acid intermediates, and dietary and bacterial fermentation products (short-chain fatty acids) at various doses and durations. The technique has superior advantages compared to classical methods since it is rapid, possesses a single organelle sensitivity, and is label- and attachment-free.

AB  - Interactions of antibiotics with biometals can affect their antimicrobial activity by changing their bioavailability, redox properties, and stability toward hydrolysis. [1,2] The pH of biological fluids can significantly affect interactions between biometals and ionizable drugs. In this study, we investigated the interactions of Fe3+ with levofloxacin in water at different pH using fluorescence spectroscopy. The coordination of Fe3+ with levofloxacin is pH dependent due to the ionization of levofloxacin and solubility of Fe3+(aq) ions. The formation of levofloxacin-Fe3+ complex was detected in the pH range 4–5 as a decrease in fluorescence intensity of levofloxacin. The Stern-Volmer diagrams of levofloxacin in the presence of different concentrations of Fe3+ ion at pH 4 and pH 5 correspond to the static fluorescence quenching confirming the coordination of levofloxacin with high-spin Fe3+. At pH < 4 and pH > 5 the addition of FeCl3 as a source of Fe3+ ions results in an increase in fluorescence intensity which can be attributed to the change of the ionic strength of solution and electrostatic interactions between different ionic species instead of coordination of Fe3+ ions with levofloxacin. The coordination of Fe3+ with levofloxacin at pH < 4 is prevented by protonation of its carboxyl and piperazinyl groups (pKa1 = 6.02, pKa2 = 8.15). At pH > 5, despite the presence of zwitterionic and anionic forms of levofloxacin available for coordination, there is no complex formation due to the precipitation of insoluble ferric hydroxide.

AB  - Predmet istraživanja ove doktorske disertacije je praćenje indikatora kvaliteta semena kukuruza(Zea mays L.) kontaminiranog aflatoksinima, u zavisnosti od koncentracije aflatoksina prisutnog usemenu. Kako se kukuruz široko koristi u ljudskoj i životinjskoj ishrani, naučne studije o sadržaju iinterakciji mikotoksina u semenima poljoprivrednih kultura su intenzivirana u poslednjoj deceniji.U okviru ove disertacije proučena je veza između nivoa kontaminacije semena kukuruza i markermolekula fenolnog tipa, ukupnog sadržaja i distribucije slobodnih organskih radikala, sadržajametala, kao i fluorescentnog emisionog profila semena kukuruza. Fokus ovog istraživanja bio je naaflatoksinu B1 (AFB1), jednom od najštetnijih prirodnih kontaminanta koji se mogu naći u semenukukuruza. Utvrđeno je da aflatoksini dovode do ozbiljnih zdravstvenih problema kod ljudi iživotinja, kao i do ogromnih ekonomskih gubitaka, kao posledica smanjenja kvaliteta semena kaostočne hrane i izvozne prehrambene robe.Prvi deo disertacije predstavlja hemijsku karakterizaciju semena kukuruza različitog nivoakontaminacije aflatoksinom. Ultraefikasnom tečnom hromatografijom sa hibridnim masenimdetektorom visoke rezolucije, koji kombinuje linearni trap-kvadrupol i orbitrap maseni analizator(UHPLC–LTQOrbiTrapXL MS), određen je fenolni profil metanolnih ekstrakata i hidrolizataispitivanih semena. Nadalje, kvalitativna i kvantitativna analiza odabranih fenolnih jedinjenja jeurađena pomoću reverzno-fazne visoko-efikasne tečne hromatografije sa ultravioletnim detektoromsa više dioda (DAD) i masenim detektorom sa jednim analizatorom (engl. single quadrupole) ielektrosprej jonizacionim (ESI) izvorom (RP-HPLC–DAD ESI–MS). Rezultati pokazuju da sukonjugati poliamina (hidroksicinamični kiseli amidi) i fenolne kiseline (ferulinska i p-kumarinska),redom, dominantna jedinjenja u metanolnim ekstraktima i hidrolizatima ispitivanih uzoraka.Utvrđeno je da sadržaj i odnos specifičnih fenolnih jedinjenja zavisi od koncentracije aflatoksina usemenu. Po prvi put, u ovoj studiji, je ustanovljena dozno-zavisna veza između odnosa zbirakonjugata putrescina i spermidina i koncentracije AFB1. Rezultati dobijeni primenom UV-VISspektrofotometrije potvrđuju postojanje dvofaznog odgovora semena na proučavani toksin. Privišim nivoima kontaminacije u spoljašnjim frakcijama semena, utvrđen je veći sadržaj lignina, kao iveća količina jedinjenja koja se u literaturi označavaju kao markeri procesa lignifikacije, upućujućina jedan od mehanizama zaštite semena. Primenom indukovano kuplovane plazme sa optičkomemisionom spektrometrijom (ICP–OES) i masenom spektrometrijom (ICP–MS), određen je sadržajmikro- i makroelemenata. Dobijeni rezultati pokazuju veći sadržaj Zn i Mn u semenima višeg nivoakontaminacije, u poređenju sa kontrolom i nisko kontaminiranim uzorcima. Na matrice HPLC i ICPpodataka, primenjena je analiza glavnih komponenti (engl. Principal component analysis, PCA) ucilju diskriminacije semena različitih nivoa kontaminacije aflatoksinom, kao i za pronalaženjemogućih markera kontaminacije. Elektronska paramagnetna rezonantna (EPR) spektroskopijaiskorišćena je za proučavanje sadržaja slobodnih organskih radikala u proučavanim uzorcima.Utvrđene su razlike u koncentraciji ovih radikala između spoljašnje i unutrašnje frakcije, kao ivarijacije u pogledu nivoa kontaminacije.Procena redoks statusa u ispitivanim semenima urađena je EPR imidžingom sa spinskim probama.Dobijeni rezultati daju doprinos razumevanju slobodno–radikalskog metabolizma i redoks statusakontaminiranih semena.Drugi deo doktorske disertacije obuhvatio je primenu naprednih metoda spektralne analize nafluorescentne emisione spektre ispitivanih uzoraka, kao što su multivarijaciona rezolucija krivihnaizmenični najmanji kvadrati (MCR–ALS), analiza glavnih komponenti, linearna diskriminacionaanaliza i druge. Ovakav način obrade podataka fluorescentnih spektara analiziranih uzoraka nije bioranije korišćen. Dobijeni rezultati se mogu uspešno koristiti kao indikator kontaminacije semenakukuruza aflatoksinom. Rezultati predstavljeni u ovoj disertaciji su od velikog praktičnog značaja,pošto osim fundamentalnih saznanja o stanju semena kontaminiranih aflatoksinima, mogu da dajuosnovu za razvoj spektroskopsko-statističkih metoda za procenu kontaminacije semena različitihpoljoprivrednih kultura.
AB  - The research topic of this doctoral dissertation is the selection of appropriate indicators for themonitoring of maize (Zea mays L.) seed contamination with aflatoxins and the examination of itsdependence on the aflatoxin concentration. As maize (Zea mays L.) is widely used in human andanimal nutrition, scientific research on the content and interaction of mycotoxins in agriculturalseeds has intensified in the last decade. Overall, the relationship between the degree of maize seeds’contamination and marker molecules of phenolic type, total content and distribution of free radicals,metal content, as well as the fluorescence emission profile of maize seeds were studied, and theresults are presented in this dissertation. The focus of this research is on aflatoxin B1 (AFB1), one ofthe most hazardous naturally occurring contaminants in maize seeds. As a naturally toxiccontaminant, it has led to adverse health effects on humans and animals, as well as to hugeeconomic losses, lowering the value of seeds as feed and as an export food commodity.In the first part of this dissertation, the chemical characterization of maize seeds of differentlevels of aflatoxin contamination was examined. Phenolic profiles of methanolic extracts andhydrolysates from aflatoxin-containing seeds were evaluated using ultra-high-performance liquidchromatography coupled to a high-resolution hybrid mass spectrometer which consists of a linearion trap-quadrupole and an Orbitrap mass analyzer (UHPLC-LTQOrbiTrapXL). Furthermore,quality and quantity analysis of selected phenolic compounds was performed by reverse-phase highperformance liquid chromatography with ultraviolet multi-diode detector (DAD) and singlequadrupole mass detector and electrospray ionization (ESI) source (RP-HPLC-DAD ESI-MS).Dominant phenolic compounds which are identified in methanolic extracts and hydrolysates ofanalysed seeds were conjugates of polyamines (hydroxycinnamic acid amides) and phenolic acids(ferulic acid and p-coumaric), respectively. The obtained results show that the content and ratiobetween specific phenolic compounds varies depending on the concentration of aflatoxins in theseed. For the first time, in this study, it is showed that level of aflatoxins has an impact on seeds'defense strategy, such as biphasic response regarding the ratio of putrescine and spermidineconjugates. Also, we showed a positive correlation between the lignin content and the AFB1concentrations in the seeds' outer fraction, which reflects the protective role of lignin during stressconditions. For the first time, in this study, it was found that aflatoxin B1 can induce a dosedependent relationship concerning specific phenolic compounds, mainly on the sum ratio betweenputrescine and spermidine conjugates in methanolic extracts. The results, obtained using UV-VISspectrophotometry, confirm the existence of a two-phase seed response to the studied stressor. Athigher levels of contamination in the outer seed fractions, higher lignin content was found, as wellas a higher amount of those compounds that are listed in the literature as lignification markers,which indicates the structural mechanism of seed protection. The content of individual micro-andmacroelements was determined using induced coupled plasma with optical emission spectrometry(ICP-OES) and mass spectrometry (ICP-MS), respectively. Obtained results show that levels of Znand Mn were higher in AFB1 high contaminated seeds compared to the control and lowcontaminated samples.

abstract = "Predmet istraživanja ove doktorske disertacije je praćenje indikatora kvaliteta semena kukuruza(Zea mays L.) kontaminiranog aflatoksinima, u zavisnosti od koncentracije aflatoksina prisutnog usemenu. Kako se kukuruz široko koristi u ljudskoj i životinjskoj ishrani, naučne studije o sadržaju iinterakciji mikotoksina u semenima poljoprivrednih kultura su intenzivirana u poslednjoj deceniji.U okviru ove disertacije proučena je veza između nivoa kontaminacije semena kukuruza i markermolekula fenolnog tipa, ukupnog sadržaja i distribucije slobodnih organskih radikala, sadržajametala, kao i fluorescentnog emisionog profila semena kukuruza. Fokus ovog istraživanja bio je naaflatoksinu B1 (AFB1), jednom od najštetnijih prirodnih kontaminanta koji se mogu naći u semenukukuruza. Utvrđeno je da aflatoksini dovode do ozbiljnih zdravstvenih problema kod ljudi iživotinja, kao i do ogromnih ekonomskih gubitaka, kao posledica smanjenja kvaliteta semena kaostočne hrane i izvozne prehrambene robe.Prvi deo disertacije predstavlja hemijsku karakterizaciju semena kukuruza različitog nivoakontaminacije aflatoksinom. Ultraefikasnom tečnom hromatografijom sa hibridnim masenimdetektorom visoke rezolucije, koji kombinuje linearni trap-kvadrupol i orbitrap maseni analizator(UHPLC–LTQOrbiTrapXL MS), određen je fenolni profil metanolnih ekstrakata i hidrolizataispitivanih semena. Nadalje, kvalitativna i kvantitativna analiza odabranih fenolnih jedinjenja jeurađena pomoću reverzno-fazne visoko-efikasne tečne hromatografije sa ultravioletnim detektoromsa više dioda (DAD) i masenim detektorom sa jednim analizatorom (engl. single quadrupole) ielektrosprej jonizacionim (ESI) izvorom (RP-HPLC–DAD ESI–MS). Rezultati pokazuju da sukonjugati poliamina (hidroksicinamični kiseli amidi) i fenolne kiseline (ferulinska i p-kumarinska),redom, dominantna jedinjenja u metanolnim ekstraktima i hidrolizatima ispitivanih uzoraka.Utvrđeno je da sadržaj i odnos specifičnih fenolnih jedinjenja zavisi od koncentracije aflatoksina usemenu. Po prvi put, u ovoj studiji, je ustanovljena dozno-zavisna veza između odnosa zbirakonjugata putrescina i spermidina i koncentracije AFB1. Rezultati dobijeni primenom UV-VISspektrofotometrije potvrđuju postojanje dvofaznog odgovora semena na proučavani toksin. Privišim nivoima kontaminacije u spoljašnjim frakcijama semena, utvrđen je veći sadržaj lignina, kao iveća količina jedinjenja koja se u literaturi označavaju kao markeri procesa lignifikacije, upućujućina jedan od mehanizama zaštite semena. Primenom indukovano kuplovane plazme sa optičkomemisionom spektrometrijom (ICP–OES) i masenom spektrometrijom (ICP–MS), određen je sadržajmikro- i makroelemenata. Dobijeni rezultati pokazuju veći sadržaj Zn i Mn u semenima višeg nivoakontaminacije, u poređenju sa kontrolom i nisko kontaminiranim uzorcima. Na matrice HPLC i ICPpodataka, primenjena je analiza glavnih komponenti (engl. Principal component analysis, PCA) ucilju diskriminacije semena različitih nivoa kontaminacije aflatoksinom, kao i za pronalaženjemogućih markera kontaminacije. Elektronska paramagnetna rezonantna (EPR) spektroskopijaiskorišćena je za proučavanje sadržaja slobodnih organskih radikala u proučavanim uzorcima.Utvrđene su razlike u koncentraciji ovih radikala između spoljašnje i unutrašnje frakcije, kao ivarijacije u pogledu nivoa kontaminacije.Procena redoks statusa u ispitivanim semenima urađena je EPR imidžingom sa spinskim probama.Dobijeni rezultati daju doprinos razumevanju slobodno–radikalskog metabolizma i redoks statusakontaminiranih semena.Drugi deo doktorske disertacije obuhvatio je primenu naprednih metoda spektralne analize nafluorescentne emisione spektre ispitivanih uzoraka, kao što su multivarijaciona rezolucija krivihnaizmenični najmanji kvadrati (MCR–ALS), analiza glavnih komponenti, linearna diskriminacionaanaliza i druge. Ovakav način obrade podataka fluorescentnih spektara analiziranih uzoraka nije bioranije korišćen. Dobijeni rezultati se mogu uspešno koristiti kao indikator kontaminacije semenakukuruza aflatoksinom. Rezultati predstavljeni u ovoj disertaciji su od velikog praktičnog značaja,pošto osim fundamentalnih saznanja o stanju semena kontaminiranih aflatoksinima, mogu da dajuosnovu za razvoj spektroskopsko-statističkih metoda za procenu kontaminacije semena različitihpoljoprivrednih kultura., The research topic of this doctoral dissertation is the selection of appropriate indicators for themonitoring of maize (Zea mays L.) seed contamination with aflatoxins and the examination of itsdependence on the aflatoxin concentration. As maize (Zea mays L.) is widely used in human andanimal nutrition, scientific research on the content and interaction of mycotoxins in agriculturalseeds has intensified in the last decade. Overall, the relationship between the degree of maize seeds’contamination and marker molecules of phenolic type, total content and distribution of free radicals,metal content, as well as the fluorescence emission profile of maize seeds were studied, and theresults are presented in this dissertation. The focus of this research is on aflatoxin B1 (AFB1), one ofthe most hazardous naturally occurring contaminants in maize seeds. As a naturally toxiccontaminant, it has led to adverse health effects on humans and animals, as well as to hugeeconomic losses, lowering the value of seeds as feed and as an export food commodity.In the first part of this dissertation, the chemical characterization of maize seeds of differentlevels of aflatoxin contamination was examined. Phenolic profiles of methanolic extracts andhydrolysates from aflatoxin-containing seeds were evaluated using ultra-high-performance liquidchromatography coupled to a high-resolution hybrid mass spectrometer which consists of a linearion trap-quadrupole and an Orbitrap mass analyzer (UHPLC-LTQOrbiTrapXL). Furthermore,quality and quantity analysis of selected phenolic compounds was performed by reverse-phase highperformance liquid chromatography with ultraviolet multi-diode detector (DAD) and singlequadrupole mass detector and electrospray ionization (ESI) source (RP-HPLC-DAD ESI-MS).Dominant phenolic compounds which are identified in methanolic extracts and hydrolysates ofanalysed seeds were conjugates of polyamines (hydroxycinnamic acid amides) and phenolic acids(ferulic acid and p-coumaric), respectively. The obtained results show that the content and ratiobetween specific phenolic compounds varies depending on the concentration of aflatoxins in theseed. For the first time, in this study, it is showed that level of aflatoxins has an impact on seeds'defense strategy, such as biphasic response regarding the ratio of putrescine and spermidineconjugates. Also, we showed a positive correlation between the lignin content and the AFB1concentrations in the seeds' outer fraction, which reflects the protective role of lignin during stressconditions. For the first time, in this study, it was found that aflatoxin B1 can induce a dosedependent relationship concerning specific phenolic compounds, mainly on the sum ratio betweenputrescine and spermidine conjugates in methanolic extracts. The results, obtained using UV-VISspectrophotometry, confirm the existence of a two-phase seed response to the studied stressor. Athigher levels of contamination in the outer seed fractions, higher lignin content was found, as wellas a higher amount of those compounds that are listed in the literature as lignification markers,which indicates the structural mechanism of seed protection. The content of individual micro-andmacroelements was determined using induced coupled plasma with optical emission spectrometry(ICP-OES) and mass spectrometry (ICP-MS), respectively. Obtained results show that levels of Znand Mn were higher in AFB1 high contaminated seeds compared to the control and lowcontaminated samples. Principal component analysis (PCA) was applied to the HPLC as well asICP results, to distinguish between seeds with different levels of aflatoxin contamination, as well asto find possible markers of seed contamination. Electron paramagnetic resonance (EPR)spectroscopy was used to study the content of free organic radicals in the studied samples.Differences in the concentration of these radicals were determined between the outer and innerfractions of seeds, as well as variations concerning the level of contamination.Estimation of redox status in the examined seeds was done by the technique of EPR imagingwith spin probes.

AB  - Metal oxide nanomaterials have gained a lot of attention during last decades due to their potential applications in wastewater treatment, energy storage, sensors, food packaging, etc. To date, these materials have been synthesized by different chemical and physical techniques. However many of them employ environmentally unfriendly solvents and toxic chemical compounds. To tackle this problem, use of renewable biomass such as plants and fungi as reducing or stabilizing agents in green synthesis has been considered as more sustainable option compared to toxic chemical compounds. These biological substances also behave as capping agent, which control the size and the shape of the nanoparticles. In this work, ZnO nanoparticles (NPs) have been prepared via simple, low cost and ecofriendly method using citrus fruit peel and extracts, Agaricus bisporus powder and extract as biological reducing agents. Zinc nitrate and zinc acetate were used as source of zinc ions. Structural and optical properties were investigated by X-ray diffraction analysis (XRD), Zeta potential, Fourier Transform Infrared (FTIR) spectroscopy, UV-visible (UV-vis) spectroscopy and Photoluminescence spectroscopy (PL). Morphological features were characterized by Field Emission Scanning Electron microscopy (FESEM) and High Resolution Transmission Electron Microscopy (HRTEM). Antibacterial and antioxidant activity was tested and evaluated.

AB  - The application of enzymes for phenol removal from polluted waters is an effective and
environmentally favorable method and an ongoing worldwide research topic. Oxidoreductive
enzymes, like Soybean peroxidase (SBP), catalyze oxidation and polymerization of phenolic
compounds in the presence of H2O2. The industrial application, however, requires enzyme
immobilization on various carriers to overcome the disadvantages of using the soluble form.
Chemically modified pectin has been chosen as a carrier for entrapment of SBP inside a threedimensional
polymeric network. Immobilization of SBP was performed in an emulsion polymerization
reaction producing enzymes entrapped in covalently crosslinked tyramine-pectin in the shape of
micro-beads. The specific activity of immobilized SBP was determined using pyrogallol as a substrate.
In this study, the stability of the immobilized SBP onto modified pectin in three different molar ratios
was tested to determine the carrier with the best performance. Immobilized peroxidase has potential
for application as a biocatalyst for phenol removal from wastewater.

AB  - Varroa infestation is considered a major threat to honeybees due to its strong impact on the colony, attacking larval cells, increasing bee mortality, and serving as a vector of pathogens. Coumaphos is an organophosphate-based acaricide insecticide which is frequently used to control Varroa (Varroa destructor) mites in the honey bee (Apis melifera) colonies. The accumulation of these lipophilic contaminants in honey and beeswax may affect honey bee health, mainly honey bee larvae which are the most sensitive, and negatively affect queen quality. In this study, we analyzed honey samples from hives of honey bees that were treated with Coumaphos, as well as the samples of pure Coumafos. The front-face fluorescence measurements of analyed honey samples were recorded using an Fl3-221 P spectrofluorimeter, with a 450 W Xenon lamp. Obtained results showed an emission peak with maximum around 400 nm, after excitation at 340 nm. It could be related to the presence of Coumaphos in honey samples, which showed the characteristic position of emission maximum at the same wavelength. These results showed that fluorescence spectroscopy may be useful as a fast and sensitive method, for the efficient and specific determination of toxic substances such as Coumaphos residues in honey. Due to the proven toxic effects on honey bees, as well as on humans, monitoring hazardous contaminants in honey is of crucial importance in the field of food and agriculture.

Due to the proven toxic effects on honey bees, as well as on humans, monitoring hazardous contaminants in honey is of crucial importance in the field of food and agriculture.",

AB  - Silica is beneficial element for plants. Many studies of silica show the useful effects that Si can provide on plant-environment relationships in a wide variety of crops, as increase in growth and yield and improvement of resistance to metal toxicity, salt stress, drought resistance etc. The occurrence of Si within a plant is a result of its uptake in the form of soluble Si(OH)4 or Si(OH)3O ion from the soil, and its polymerization at a final location. Si is mostly accumulated in the cell walls (CWs), thus providing strengthening of CWs, increasing mechanical strength, and alleviating effects of various biotic and abiotic types of stress. Lignin, as one of the main components of the plant CW, is a natural phenolic polymer with high molecular weight and complex structure. Accumulation of silica in plants is directly connected with chemistry and structure of lignin. Silicon affects the composition of CWs by its binding to the phenolic and carbohydrate CW components in polymerization reactions by altering linkages of non-cellulosic polymers and lignin. We studied, in an in vitro system, the interaction of SiO2 with the peroxidase catalyzed polymerization of a lignin monomer into the lignin model compound (DHP). Fluorescence microscopy and spectroscopy combined with AFM technique showed that Si was bound to the final polymer, and the structure of the Si-DHP differed from pure DHP. We show that Si significantly influence on lignin structure. The results contribute to understanding of Si binding to lignin in cell walls, which may have impact on possible Si applications in agriculture.

AB  - Mung bean (Vigna Radiata L.) seeds are an important source of both nutrients (such as proteins, fibers, vitamins) and a variety of bioactive compounds (like phenolic compounds). Ultraviolet (UV) light has an important function as a major environmental signal important for plant growth and development, but at the same time it may cause certain damaging effects on macromolecules and other cellular components. Plants respond to the production of reactive oxygen species (ROS), caused by UV irradiation, by activating changes in morphology, physiology, or production of secondary metabolites. Some of these mechanisms increase antioxidant capacity in order to reduce the harmful effect of produced ROS. In the present research, the duration of exposure to UV-A irradiation and its influence on antioxidant activity of mung bean seeds were studied. Seeds were exposed to constant irradiation for 1 or 3 hours using a UV-A lamp (93μW/cm2) at a 50 cm distance. Antioxidant activity was tested using DPPH (2,2-Diphenyl-1-picrylhydrazyl) assay. The results indicate a significant increase in antioxidant activity of the UV-A irradiated seeds after 1 hour (74,45 % ± 0,40), compared to the control (72,85 % ± 1,55). After prolonged exposure, measured antioxidant activity significantly increased (77,99 % ± 0,71). Our results show a correlation between duration of UV-A irradiation and the increase in antioxidant activity. This could be beneficial in agriculture for producing fortified food.

AB  - Mung bean (Vigna radiata L.) is a leguminous plant with high nutritional value, traditionally known as a functional food. Legume seeds are a rich source of proteins, vitamins, minerals, and essential amino acids but also contain bioactive components and polyphenols which possess a high antioxidant capacity. Pigments content (chlorophyll a and b, carotenoids) was determined as good parameter for estimation of seed quality and an indicator of tolerance to different types of stress. The antioxidant activity of the seeds was determined using DPPH (2, 2-diphenyl-1-picrylhydrazyl) assay. The concentration of chlorophile a and b and carotenoids were determined by a spectrophotometric method. Obtained results indicate a higher content of chlorophyll a than chlorophyll b, 0.352 μg/ml and 0.220 μg/ml respectively, while total carotenoids content was 0.108 μg/ml and DPPH radical scavenging activity was 54.52% ± 1.77. The advancement in this research lies in collecting information about bioactive compounds, such as chlorophylls and carotenoids, that are useful in improving the functional and antioxidant properties of quality seeds used in daily diet.

AB  - Plant secondary metabolism, as well as the growth and development of specific photomorphogenic
responses, can be induced by UV light. The effects of UV-A and UV-B irradiations on the antioxidant activity and fluorescence characteristics of Glycine max L. seeds were investigated for two different exposure periods (1, 3 h). The antioxidant activity and photoluminescent characteristics of irradiated seeds were evaluated by the DPPH (2,2'-diphenyl-1-picrylhydrazyl radical) assay and excitation-emission matrices (EEMs) fluorescence spectroscopy, respectively. The DPPH scavenging activity significantly increased with exposure time in the UV-A treated seeds, while variations were observed after UV-B treatment. EEM showed three main peaks characterized with excitation/emission 280/355 nm (Peak A), 290/400 nm (Peak B), and 370/465 nm (Peak C). The most prominent change in fluorescence intensity was observed in peak B. Obtained results indicate that the type of UV radiation, as well as period of exposure, induce biochemical and biophysical changes in the soybean seeds.

AB  - In this preliminary study, we applied the Multivariate Curve Resolution- Alternating Least Squares (MCR-ALS) method to analyze the excitation-emission matrices of multifloral honey samples, combined with differential scanning calorimetry (DSC) to estimate infection of honey bee colonies with N. ceranae or V. destructor. Fluorescence spectroscopy combined with MCR-ALS was used to determine the ratio of the spectral components originating from proteins (C1) and phenolics (C2), two minor but essential constituents of honey, as a ratiometric indicator of infection level in related hives. The C1/C2 ratio decreased linearly with the increase of infection in both N. ceranae and V. destructor cases, the R (2) was 0.941 and 0.912, respectively. Additionally, DSC has shown that the magnitude of changes in sugar environments of the honey samples, reflected in sugar phase transitions, rises with increasing infection level in bee colonies. These results indicate that fluorescence combined with MCR-ALS could be used for rapid, non-destructive and cheap screening of honey to estimate the level of infection of honey bee colonies.
