AB  - Cerium oxide nanoparticles (nCeO2) are interesting nanomaterials due to their redox properties. Their wide application could result in unexpected consequences to environmental safety. Unlike acute toxicity, the trans-generational effects of carbohydrate-coated nCeO2 in the environment are still unknown. The main aim of this study was to investigate the effect of treating maternal plants of Chenopodium rubrum L. (red goosefoot) and Sinapis alba L. (white mustard) with uncoated (CeO2) and glucose-, levan-, or pullulan-coated nCeO2 (G-, L-, or P-CeO2) during seed germination on morphological and physiological characteristics of produced seeds in two subsequent generations. The plant response was studied by measuring germination percentage (Ger), total protein content (TPC), total phenolic content (TPhC), total antioxidative activity (TAA), and catalase (CAT) activity. Results showed that maternal effects of the different nCeO2 treatments persist to at least the second generation in seeds. Generally, C. rubrum was more sensitive to nCeO2 treatments than S. alba. The coated nCeO2 were more effective than uncoated ones in both plant species; L- and P-CeO2 were the most effective in S. alba, while CeO2 and G-CeO2 had a dominant impact in C. rubrum. Enhanced germination in all tested generations of S. alba seeds recommends nCeO2 for seed priming.

AB  - Bacterial and fungal resistance is an increasingly severe problem. The high microbial resistance appears to be the consequence of the unconsidered use of antibiotics and antifungal drugs, and poor infection control in hospitals. Fighting microbial resistance by using new substances based on organic nanoparticles, carbon dots (CDs) may be a promising strategy in developing new therapeutic approaches. The metal-organic frameworks (MOFs), due to their unique features including high cargo loading, biodegradability, and ability of modification have become an attractive group of nanomaterials used in several fields including nanomedicine. In the current study, we synthesized N- and S-CDs@AgMOFs nanocomposites, new substances based on organic CDs nanoparticles inserted in MOFs structures. One Gram-positive (Bacillus subtilis), one Gram-negative (Escherichia coli) bacteria, and one fungi (Candida albicans) were treated with different concentrations (15.625, 31.25, 62.5, 125, 250, 500, 1000, and 2000 mg/L) of N- and S-CDs@AgMOFs nanocomposites during 48 h. The results showed the bactericidal effect of N- and S-CDs@AgMOFs on Bacillus subtillis and the antifungal effect on Candida albicans. The effect of S-CDs@AgMOFs was stronger on bacterial cells compared to the N-CDs@AgMOFs, while both agents affected fungi in equal concentrations, indicating different mechanisms in the two types of microorganisms. In Candida albicans, minimal inhibitory concentration (MIK) of both nanocomposites was 125 mg/L, while in Bacillus subtilis MIK of N-CDs@AgMOFs was 500 mg/L and for S-CDs@AgMOFs was 250 mg/L. It can be concluded that tested nanocomposites are safe for the environment because they are not toxic in the concentrations in which they can be found in the environment.

AB  - The various applications of cerium oxide nanoparticles (nCeO2), one of the most produced metal oxide nanoparticles, could affect environmental health due to accumulation of uncoated and coated nCeO2 with increased suspension stability. The trans-generational effects on seed characteristics are important components of the life histories of plants representing the pathway from adult to offspring that completes the life cycle. The effects of carbohydrate-coated nCeO2 on the plant seeds through the generations are still unknown. The main aim of this study was to investigate the effect of the treatment of maternal Sinapis alba and Chenopodium rubrum plants with 200 mg/L of uncoated (CeO2) and glucose-, levan-, or pullulan coated nCeO2 (G-, L-, оr P-CeO2) on germination of three generations of seeds. Sinapis alba was selected as a hyperaccumulator of heavy metals, while Chenopodium rubrum was selected as a short-day plant and weed. In Sinapis alba, the results of germination on the 4th day revealed increased germination after the treatment with CeO2 and L-CeO2 nanoparticles in zero generation and after all nCeO2 treatments in the 1st and 2nd generation of seeds. In Chenopodium rubrum, there were no changes after the treatments. It can be concluded that trans-generational effects of the different nCeO2 treatments persist to at least the second generation in seeds. Compared to the same generation control, the 2nd generation of seeds showed the highest sensitivity. The coated nCeO2 were more effective than the uncoated ones. Enhanced germination in three generations of S. alba seeds recommends nCeO2 for application in seed-priming.

AB  - Manganese (Mn) is an essential element for plant growth. For metabolic function, Mn2+ is required at low concentrations, but Mn2+ excess can change the activity of various enzymes and interfere with the absorption and translocation of some minerals such as Ca, Mg, Fe, and P. Mn availability to the plants depends on pH of the growth medium and on root exudates for Mn chelation or reduction. The main aim of this research was to investigate the effect of Mn2+ on the main parameters of secondary metabolism: total phenolic content (TPC) and total antioxidative activity (TAA) in maize (Zea mays L.) shoots and roots. Maize was chosen as agricultural species important for human and animal nutrition, and a simply cultivated plant. Maize seeds (inbred line Va35) were germinated in distilled water and then transferred into the hydroponic (KNOP/2) growth solution. Mn2+ was applied in two different concentrations (5 and 100 μM) by adding MnSO4 into the hydroponic solution. After 7 days (December 2021) of growing under 8/16h photoperiod, the leaves and roots were collected. The TPC was measured according to Folin-Ciocalteu’s spectrophotometric procedure, while TAA was determined by ABTS/HRP assay. The results showed that TAA was significantly decreased only in maize roots after the treatment with 5 μM Mn2+, while higher Mn2+ concentration (100 μM) did not change TAA in maize roots. TAA in shoots and TPC in both parts of maize was unchanged. Finding that 5 μM of Mn2+ have decreasing effect on maize antioxidative activity without harming plants indicates that lower concentration can be more toxic due to: 1. plants excreting an excess of Mn2+ into the environment after the treatment with high Mn2+ concentration and 2. Mn can affect the metabolism of small molecules (enzymes or phytochelatins) binding for them and decreasing the total ROS scavenging activity.

AB  - Plant nanobionics studies nanoparticles application toplants, which improves certain plant functions. Due to many limitations, plants use less photosynthetic capacity thanit is theoretically possible, so an increase in leaf photosynthesis canbe important for increasing crop yield. For this purpose, carbon dots (CDs) as organic, non-toxic nanoparticles with a huge potential for application can be used. They are a green alternative to metal nanoparticles. The main advantages of these nanoparticles are their easy preparation, high water solubility, biocompatibility, and photoluminescence. The main aim of this research was to investigate the effect of orange carbon dots (o-CDs), synthesized from citric acid and o-phenylenediamine as precursors, on photosynthetic efficiency increase in maize (Zea mays L.), as a model plant and agricultural species. We applied o-CDs in three different concentrations (1, 5, and 10 mg/L) by adding to the hydroponic growth solution or foliarly. The photosynthesis parameters (photosynthetic rate, transpiration rate, water use efficiency) and content of photosynthetic pigments (chlorophyll a and b, carotenoids) were recorded. The results showed that the photosynthetic parameters’ values were higher for foliar than for solution application. Amount of 1 mg/L o-CDs applied foliarly and 5 mg/L in solution increased photosynthetic parameters in leaves. The photosynthetic pigments were enhanced after o-CDs treatments. Finding that o-CDs have photosynthesis enhancing potential without harming plants opens new opportunities in their use in agricultural applications, such as increasing plant productivity.

AB  - Cerium oxide nanoparticles (nCeO2) are attracting continuously growing attention due to their unique properties  - their facile transition between Ce3+ and Ce4+ oxidation states. nCeO2 found application in the industry, cosmetics, agriculture, electronics, etc.  Their final accumulation in the environment creates new environmental stress factors for living organisms. To improve their solubility, nCeO2 were coated with monosaccharide - glucose and microbial exopolysaccharides - levan and pullulan to obtain glucose-, levan-, and pullulan-coated nCeO2 (G-CeO2, L-CeO2, and P-CeO2). The potential long-term effect of nCeO2 on vegetation was studied in two herbaceous weedy annuals - Sinapis alba and Chenopodium rubrum. It was suggested earlier that the mechanism of maternal environmental effects, that persists for several generations, can act through relative seed protein composition representing an “archive“ of environmental changes experienced by mother plants during their lives. Treatment with nCeO2 of Sinapis alba and Chenopodium rubrum seeds during germination, on total protein content (TPC) and protein profile of seeds produced in two subsequent offspring generations grown in the greenhouse, were investigated. The TPC mainly showed no significant differences, both between treatments and between subsequent generations, in both species. SDS-PAGE electrophoresis showed the presence of 15 protein bands, molecular weight 10 - 140 kDa, in all seed samples of Sinapis alba or Chenopodium rubrum, respectively. We showed that nCeO2 treatment during the very early development of mother plants (germination) has a long-term effect, visible in the difference in width and intensity of seed protein bands of seeds sampled in two subsequent offspring generations.

AB  - Cerium oxide nanoparticles (nCeO2) are nanomaterial widely used in electronics, cosmetics, catalysis, and fuel additives production due to their transition between Ce3+ and Ce4+ oxidation states. Their increasing production (around 10,000 metric tons per year) makes them one of the most produced metal oxide nanoparticles which can lead to unexpected consequences to environmental health and safety. Coating nCeO2 with different polymers is a very popular way to increase their suspension stability, but the data on their effect on cultivated plants are scarce. Environmental effects on morphological and physiological properties of offspring which occur during the development of the mother plant are called maternal environmental effects. Their expression depends on the offspring’s environment, they are expressed throughout the life cycle of the offspring and may persist for several generations. It was suggested that components of the nonenzymatic antioxidant system might participate in the mechanism governing the maternal environmental effects. Total antioxidant activity (TAA) comprises the contribution of different non-enzymatic components with antioxidant capacity. Herbaceous weedy annuals Sinapis alba and Chenopodium rubrum were selected, as a heavy metal hyperaccumulator plant i.e. a species with strong maternal effects, respectively. The effect of uncoated (CeO2) and glucose-, levan-, and pullulan- coated nanoparticles (G-CeO2, L-CeO2, P-CeO2) treatment of Chenopodium rubrum and Sinapis alba seeds during germination, on TAA of seeds produced in two subsequent generations of plants grown in a greenhouse, were investigated. TAA was measured using the ABTS/HRP end point method. Results showed that the effect of nCeO2 treatments was more expressed in Sinapis alba seeds; mainly all nanoparticles treatments during germination of mother plants resulted in the increase in TAA of produced seeds in both monitored generations. In contrast, in Chenopodium rubrum CeO2 treatment resulted mainly in the decrease in TAA of produced seeds in both monitored generations. The presented effect was equally expressed in both generations. Among nanoparticles, L-CeO2 showed the most pronounced effect in both generations of the plants. We showed that the effect of nCeO2, applied during the early development of mother plants (germination), is visible in changes in the components of the nonenzymatic antioxidant system of produced seeds and that it persists for (at least) two generations. In other words, seed priming with nCeO2 might affect changes in yield antioxidant capacity through several generations.

AB  - INTRODUCTION:
Carbon dots (CDs) are considered a green alternative to metal nanoparticles because they can be used where metal nanoparticles cannot be applied. Orange carbon dots (CDs), synthesized from citric acid and o-phenylenediamine as precursors, are organic spherical nanoparticles with a lot of applications in various biomedical purposes such as drug delivery, bioimaging, and sensing. Ease of preparation, high photoluminescence, solubility in water, and biocompatibility are their main advantages.
OBJECTIVES:
The main aim of this research was to investigate the effect of oCDs on total phenolic activity (TPC) in maize as an agricultural species. TPC reflects the contribution of phenolics as a group of secondary metabolites participating in the regulation of plant growth and in the defense responses. Also, it is one of the main indicators of oxidative stress which can cause a metabolic disorder in plants.
METHOD / DESIGN:
Three different concentrations (1, 5, and 10 mg L-1) of oCDs nanoparticles were used for the treatment of maize plants via KNOP/2 hydroponic solution during 2 week-growth under 16 h/8 h photoperiod. TPC was analyzed from phenolic extracts obtained from the roots and leaves of plants after foliar and solution treatments. Folin-Ciocalteu’s spectrophotometric procedure was used for the determination of TPC in the samples.
RESULTS:
The results showed that foliar applications with all concentrations of o-CDs induced decreases of TPC in maize leaves but did not affect these parameters in the roots. In solution treatment, the concentration of 1 mg/L of o-CDs increased TPC in the leaves, but decreased in roots.
treatment
CONCLUSIONS:
The higher efficiency achieved with the lowest o-CD concentration (1 mg/L) in foliar treatment makes this way of application advantageous compared with the solution counterpart.

AB  - Fingerprints analysis has been used as a powerful and reliable tool for individual identification in forensic science for more than a century. Some traditional techniques used toxic agents, so the application of fluorescent biocompatible materials, such as N-Carbon Dots (N-CDs), can be used as-received and it is non-toxic, as opposed to a lead carbonate powder routinely used by the police. N-CDs have recently gained the attention of scientists because of their stable luminescence, hydrophilicity, chemical inertness, photo-bleaching resistance, easiness of their functionalization, and low cost. In this research, N-CDs were obtained in a simple step process using the hydrothermal treatment of polyvinylpyrrolidone (PVP), as an N source, and further used for the detection of fingerprints through fluorescent imaging. A brightness emission at 495 nm of N-CDs was related to their structural and chemical properties. Detailed surface characterizations with ss-NMR, XPS, and fluorescence spectroscopies, suggested that the negative charge of the functional groups promoted electrostatic interactions between the charged N-CDs surface functional groups (amine, carboxylic, and amide) and the secretion components present in the thin layer of fluid left on the surface upon its direct contact with human fingers. Based on biometric identification, the obtained results were validated by the scientific protocol of the Police Automated Fingerprint Identification System (AFIS).

AB  - Copper (Cu) is an essential microelement in various processes in the cell wall, such as wall synthesis and loosening, but Cu excess due to human activities increase soil pollution and can induce harmful effects. Alleviation of Cu toxicity could be ameliorated in various ways such as adding organic compounds and cations (Ca2+, Mg2+). This study aimed to reduce Cu toxic effects using organic nanoparticles as potential nano-fertilizers obtained from folic acid. Carbon dots (CDs) are biocompatible and non-toxic nanoparticles with chemical affinity to some heavy metals. In this research, CDs were applied in two different concentrations - 167 mg/L and 500 mg/L with or without 5 µM Cu2+ during the growth of maize plants in hydroponic solution. Cu concentration in plants and parameters of secondary metabolism - total phenolic content (TPC) and total antioxidative activity (TAA) were measured. Results showed that CDs based on folic acid were transported through maize and were present in both roots and leaves after 7 day-treatment. Cu concentration in roots was higher in both Cu and Cu/ 500CDs treatments compared to the control. The application of CDs reduced Cu concentration at the root level, while no significant effect was observed in leaves. However, the application of CDs was not effective in the mitigation of the oxidative stress in both roots and leaves induced by excess Cu. CDs neither affected TPC nor alleviated the TPC increase caused by Cu. Also, CDs did not cancel the TAA increase induced by Cu in any of the applied concentrations. In the leaves, TAA increased in all treatments when Cu was present in the growth medium. There were no visual adverse effects on plants.

AB  - Carbon dots (CDs) are spherical organic nanoparticles with a huge potential for application in various biomedical purposes such as sensing, bioimaging, and drug delivery, as well as in water remediation. The discovery of CDs was very popular in the 21th century because they can be used where metal nanoparticles cannot be applied, so they are considered as their green alternative. The main advantages of these nanoparticles are their ease of preparation, solubility in water, high photoluminescence, and biocompatibility. Having all these properties in mind, the main aim of this research was to investigate the effect of orange carbon dots (oCDs), synthesized from citric acid and o-phenylenediamine as precursors, on total antioxidative activity (TAA) in maize as a model plant and agricultural species. We tested antioxidative activity as an indicator of oxidative stress and metabolic disorder in plants. TAA mainly includes the contribution of different non-enzymatic components with antioxidant capacity (vitamins, phenolic acids, sugars, etc.). The maize plants were exposed to three different concentrations (1, 5, and 10 mg L-1) of oCDs nanoparticles via KNOP/2 hydroponic solution during growth under 16 h/8 h photoperiod. After the 2 week-growth,  the leaves and roots of plants were separately harvested and collected. The results showed that oCDs did not induce any change in TAA in the leaves, but increased TAA in roots after the treatment of plants with 5 and 10 mg L-1 oCDs. It can be concluded that plant treatment with oCDs’ concentrations ≥ 5 mg L-1 leads to the increase of oxidative stress in roots as a plant organ more exposed to the nanoparticles.

abstract = "Carbon dots (CDs) are spherical organic nanoparticles with a huge potential for application in various biomedical purposes such as sensing, bioimaging, and drug delivery, as well as in water remediation. The discovery of CDs was very popular in the 21th century because they can be used where metal nanoparticles cannot be applied, so they are considered as their green alternative. The main advantages of these nanoparticles are their ease of preparation, solubility in water, high photoluminescence, and biocompatibility. Having all these properties in mind, the main aim of this research was to investigate the effect of orange carbon dots (oCDs), synthesized from citric acid and o-phenylenediamine as precursors, on total antioxidative activity (TAA) in maize as a model plant and agricultural species. We tested antioxidative activity as an indicator of oxidative stress and metabolic disorder in plants. TAA mainly includes the contribution of different non-enzymatic components with antioxidant capacity (vitamins, phenolic acids, sugars, etc.). The maize plants were exposed to three different concentrations (1, 5, and 10 mg L-1) of oCDs nanoparticles via KNOP/2 hydroponic solution during growth under 16 h/8 h photoperiod. After the 2 week-growth,  the leaves and roots of plants were separately harvested and collected. The results showed that oCDs did not induce any change in TAA in the leaves, but increased TAA in roots after the treatment of plants with 5 and 10 mg L-1 oCDs. It can be concluded that plant treatment with oCDs’ concentrations ≥ 5 mg L-1 leads to the increase of oxidative stress in roots as a plant organ more exposed to the nanoparticles. This research opens new possibilities in the uses of oCDs in agricultural applications.",

AB  - Plants accumulate and synthesize various compounds, which are involved in plant-environment interaction. Among them are semi-volatile organic compounds of which 1700 are currently known to be emitted by plants. These compounds present 1% of plant secondary metabolites. The effect of cerium oxide nanoparticles (nCeO2) on semi-volatile organic compounds in plants was not investigated. Redox properties of nCeO2, based on their facile transition between Ce3+ and Ce4+ oxidation states are the main reason for their increased usage in the pharmaceutical industry, paints, cosmetics, electronics, and fuel additives. For that reason, nCeO2 can be found in the environment so there is a need to analyze their ecotoxicity. To improve their solubility, nCeO2 were coated with monosaccharide - glucose and microbial exopolysaccharides – levan, and pullulan. The main aim of this research was to study the effect of 200 mg/L glucose-, levan-, and pullulan-coated nCeO2 (G-CeO2, L-CeO2, and P-CeO2) in the shoot extracts of wheat and pea by screening the semi-volatile compounds with comprehensive two-dimensional gas chromatography (GC×GC-MS). The nCeO2 were applied at a concentration of 200 mg/L during three weeks of plants’ growth in hydroponics. The semi-volatile organic compounds were extracted from plant shoot extracts with methylene-chloride. Noticed coated nCeO2 effect was compared with the effect of uncoated ones. Nonlinear principal component analysis (NLPCA) with optimal scaling was used for the evaluation of wheat and pea GC×GC chromatograms and the confirmation of differences in chemical composition between untreated and treated plants. Results revealed that wheat samples had a higher number of chemical compounds than a pea. The chemical composition of wheat was less affected by the treatments with coated nanoparticles compared to pea. Most compounds which content was significantly different compared to the control compounds were detected in wheat after the treatment with L-CeO2 and P-CeO2, and in pea after L-CeO2 treatment. A semi-volatile profile was presented only as categorical variables, while unique fingerprint images were used for the inter-cultivar recognition. These results showed that GC×GC-MS as a screening method may be useful for monitoring the effects of various abiotic factors on different plant species.

AB  - Literature data about semi-volatile organic compounds in plants and the effect of cerium oxide nanoparticles on them are scarce. Surface modification of nanoparticles may change nanoparticle-environment interaction, and therefore affects compounds in plants. In this research, uncoated and glucose-, levan-, and pullulan-coated cerium oxide nanoparticles were used for wheat and pea treatment during the growth. The aim was the screening of semi-volatile organic compounds from plants' shoots using comprehensive two-dimensional gas chromatography-mass spectrometry, a powerful separation technique allowing to reach unique separation resolution, and investigation of qualitative changes after the treatmentwith coated cerium oxide nanoparticles. The resultswere analyzed by the identification of individual peaks and fingerprint analysis by image processing. Wheat samples contained a higher number of semi-volatile organic compounds (108) compared to pea (77) but were less affected by the treatments with coated nanoparticles. The highest number of compounds was detected in wheat after the treatment with levan- and pullulan-coated nanoparticles, and in pea after treatment with levan-coated nanoparticles. This article reports a successful application of a semi-volatile organic compounds profile presented only as categorical variables and unique fingerprint images for the inter-cultivar recognition. This method may be useful in screening nanoparticles' effects on different plants.

AB  - Carbon dots are biocompatible and non-toxic nanoparticles with chemical affinity to some heavy metals. Human activities increase soil pollution with copper. Cu is an essential microelement in plants, but excess can induce a harmful effects. In plant response to Cu, the cell wall plays an important role. This study aims to estimate possible amelioration effects of folic acid based CDs on Cu toxicity by studying the intracellular and cell wall compounds in maize (Zea mays L.) roots and leaves after 7 day-treatment in hydroponics. The sub-cellular compartmentalization and bio-macromolecular changes induced by 5 mu M Cu applied alone or with CDs (167 and 500 mg/L) were studied using the Synchrotron-based Fourier transformmicro-spectroscopy (SR-FTIR) combined with X-Ray photoelectron spectroscopy (XPS). Cu induced changes in content of cell wall polysaccharides, proteins, and lipids. The XPS detected CDs transport throughout the plants. The Cu/167CDs treatment reduced Cu concentration in the roots, possibly by complexation/trapping between the functional groups on CDs surface and Cu2+. Principal component analysis of FTIR spectra confirmed that Cu/500CDs treatment increased Cu adverse effects in most tissues but alleviated adverse Cu effects on cell wall polysaccharides in the root xylem, and on polysaccharides and proteins in leaf phloem and mesophyll.

AB  - Cerium oxide nanoparticles (nCeO(2)) have widespread applications, but they can be hazardous to the environment. Some reports indicate the toxic effect of nCeO(2) on tested animals, but literature data are mainly contradictory. Coating of nCeO(2) can improve their suspension stability and change their interaction with the environment, which can consequently decrease their toxic effects. Herein, the exopolysaccharides levan and pullulan, due to their high water solubility, biocompatibility, and ability to form film, were used to coat nCeO(2). Additionally, the monosaccharide glucose was used, since it is a common material for nanoparticle coating. This is the first study investigating the impact of carbohydrate-coated nCeO(2) in comparison to uncoated nCeO(2) using different model organisms. The aim of this study was to test the acute toxicity of carbohydrate-coated nCeO(2) on the bacterium Vibrio fischeri NRRL B-11177, the crustacean Daphnia magna, and zebrafish Danio rerio. The second aim was to investigate the effects of nCeO(2) on respiration in Daphnia magna which was performed for the first time. Finally, it was important to see the relation between Ce bioaccumulation in Daphnia magna and Danio rerio and other investigated parameters. Our results revealed that the coating decreased the toxicity of nCeO(2) on Vibrio fischeri. The coating of nCeO(2) did not affect the nanoparticles' accumulation/adsorption or mortality in Daphnia magna or Danio rerio. Monitoring of respiration in Daphnia magna revealed changes in CO2 production after exposure to coated nCeO(2), while the crustacean's O-2 consumption was not affected by any of the coated nCeO(2). In summary, this study revealed that, at 200 mg L-1 uncoated and carbohydrate-coated nCeO(2) are not toxic for the tested organisms, however, the CO2 production in Daphnia magna is different when they are treated with coated and uncoated nCeO(2). The highest production was in glucose and levan-coated nCeO(2) according to their highest suspension stability. Daphnia magna (D. magna), Danio rerio (D. rerio), Vibrio fischeri (V. fischeri)

AB  - Cerium oxide nanoparticles (nCeO2) аре popular nanomaterial due to their transition between Ce3+ and Ce4+ oxidation states. However, low stability and agglomeration of nCeO2 is a main barrier to their various application. In the first part, nCeO2 were synthesized by a self-propagating room temperature method. The nanoparticles were coated with glucose, levan or pullulan due to their high hydrosolubility and biocompatibility. Pululan was used for nCeO2 coating for the first time. nCeO2 were coated during and after the synthesis under different conditions (coating time, temperature and amount of coating material). In the second part, the uncoated and glucose-, levan- and pullulan-coated nCeO2 were characterized by scanning and transmission electron microscopies, X-ray diffraction, Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, nuclear magnetic resonance, dynamic light scattering method, and turbidimetry. Carbohydrates-coated nCeO2 after the synthesis during 6h, were further examined. In the third part, the effect of uncoated and coated nanoparticles was tested on four plant species by treatment during the germination (3 - 5 days) and the growth (3 weeks). The influence of coating on the nanoparticles’ uptake, plants’ germination and development, as well as parameters of secondary metabolism (total and individual phenols, and total antioxidant activity) was tested. Also, screening of semi-volatile compounds in wheat and pea were carried out by comprehensive two-dimensional gas chromatography. The acute toxicity of nanoparticles were tested on bacteria (Vibrio fischeri), water flea (Daphnia magna), and zebrafish (Danio rerio). The O2 and CO2 metabolic pathways in Daphnia magna were followed by respirometry.

AB  - Reports about the influence of cerium-oxide nanoparticles (nCeO(2)) on plants are contradictory due to their positive and negative effects on plants. Surface modification may affect the interaction of nCeO(2) with the environment, and hence its availability to plants. In this study, the uncoated and glucose-, levan-, and pullulan-coated nCeO(2) were synthesized and characterized. The aim was to determine whether nontoxic carbohydrates alter the effect of nCeO(2) on the seed germination, plant growth, and metabolism of wheat and pea. We applied 200 mgL(-1) of nCeO(2) on plants during germination (Ger treatment) or three week-growth (Gro treatment) in hydroponics. The plant response to nCeO(2) was studied by measuring changes in Ce concentration, total antioxidative activity (TAA), total phenolic content (TPC), and phenolic profile. Our results generally revealed higher Ce concentration in plants after the treatment with coated nanoparticles compared to uncoated ones. Considering all obtained results, Ger treatment had a stronger impact on the later stages of plant development than Gro treatment. The Ger treatment had a stronger impact on TPC and plant elongation, whereas Gro treatment affected more TAA and phenolic profile. Among nanoparticles, levan-coated nCeO(2) had the strongest and positive impact on tested plants. Wheat showed higher sensitivity to all treatments.

AB  - Cerium oxide nanoparticles (nCeO2) are nanomaterial with various applications in biomedicine, electronics and cosmetics. The aim of this research was to improve their low suspension stability by coating with carbohydrates - glucose, levan, and pullulan. The coating was performed at different temperatures and coating times, by adding the carbohydrates during or after the synthesis of nCeO2. Characterization of nanoparticles’ powders was performed by X-Ray diffraction analysis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Nanoparticles’ suspension stability was estimated by measuring of zeta potential, hydrodynamic size and turbidity. The difference among coated nCeO2 have been confirmed with FT-IR spectra. The results showed improved stability of the nCeO2 suspension and decreased size of aggregates after carbohydrate coating. Levan- and glucose-coated nCeO2 suspensions showed the best stability. The obtained nCeO2 were used for the investigation of their ecotoxicity on different plant species.

AB  - Carbon dots (CDs) are popular and emerging nanomaterial which found application in many fields such as drug delivery, optoelectronic, and imaging due to their high solubility, low cost and easiness of their functionalization. Their effect on plants is not sufficiently investigated, so it is necessary to investigate their ecotoxicity. In this research, CDs prepared from folic acid was used for the treatment of maize plants with two different concentrations. The treatment was performed during the plant growth in hydroponics. ICP method was used for the analysis of macronutrients (Ca, K, Mg, P, S) uptake in plants from the hydroponic medium, which was used for the plant growth. The obtained TPC results demonstrated low oxidative stress proportional to the used concentration, which was not significant. The similar trend was observed in TAA where the only significant increase was in plant shoots after the treatment at 500 µg L-1.

AB  - Cerium oxide nanoparticles (nCeO2) are biomaterials with numerous applications in biomedicine, fuel additives and electronics. Since their low stability in aqueous media limited their practical application, the aim of this study was to improve the suspension stability of nCeO2 by coating the particles. Glucose, monosaccharide, and levan and pullulan, microbial polysaccharides, were used as coating material. The coating was attempted under different synthesis conditions, by adding the carbohydrates during (direct coating) or after (subsequent coating) the synthesis of nCeO2. X-Ray diffraction analysis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used for characterization of nanoparticles’ powders. Measuring of hydrodynamic size, zeta potential and turbidity was used for the estimation of nanoparticles’ suspension stability in aqueous media. The success of subsequent coating with carbohydrates and the differences between coated nCeO2 have been proven with FT-IR spectra. Turbidity measurement showed the best stability of levan- and glucose-coated nCeO2 suspensions. It can be concluded that coating with carbohydrates improved the stability of the nCeO2 suspension by decreasing the size of aggregated particles. The obtained results open new horizons for further ecotoxicity investigation and nCeO2 application.

AB  - Carbon Dots (CDs) were obtained using a hydrothermal method and used for the detection of finger-prints through fluorescent imaging. Synthesized CDs exhibited a brightness emission at 495 nm, which was related to their structural and chemical properties. The results of detailed surface characterizations by XPS, ss-NMR and fluorescence spectroscopies, suggested that the negative charge of the functionals groups promoted electrostatic interactions between the charged CDs surface functional groups (amine, amide and carboxylic) and the secretion components present in the thin layer of fluid left on the surface upon its direct contact with human fingers. The obtained results were validated by the scientific protocol of the Police Automated Fingerprint Identification System (AFIS) based on a biometric identification.

AB  - Cerium oxide nanoparticles (nCeO2) have been widely investigated because of their unique property - transition between Ce3+ and Ce4+ oxidation states which allows them multiple applications, such as a catalyst, an electrolyte material in fuel cells, for drug delivery, in agriculture (fertilizer, pesticides) etc. Despite these facts, the main restriction of nCeO2 application is their tendency for agglomeration, which led many researchers to coat them with different polymers. But literature data about the impact of coated nanoparticles on plant metabolism are scarce. Also, enhanced nCeO2 application has become the risk for the environment due to their accumulation in soil, air and water. Metal toxicity may lead to overproduction of reactive oxygen species (ROS) causing the  abiotic stress and damage of important biological molecules in crop species.
In current research, we performed a three week treatment of wheat and pea seedlings in hydroponics with 200 mgL-1 uncoated and glucose-, levan- and pullulan coated nCeO2 (G-CeO2, L-CeO2 and P-CeO2). Our goal was to study the impact of nanoparticles coating on Ce uptake, and on changes in total phenolic content (TPC), as indicator of oxidative stress, in monocotyledonous and dicotyledonous crop species. ICP-OES was used for determination of Ce concentration in shoots of treated crop species.
The uptake of Ce was different among treated crop species. Ce uptake was increased after coating in pea, but decreased in wheat. High Ce content detected in wheat, caused the increase in shoot elongation without the effect on TPC. On the other hand, low Ce content measured in pea, had  no influence on shoot elongation as well as TPC. 
Presented results suggest the difference in nCeO2 uptake and their effect on morphological parameters of plant without the impact on phenolic metabolism. Despite these results, further research is necessary.

AB  - Cerium oxide nanoparticles (nCeO2) are interesting due to redox property - transition between Ce3+ and Ce4+ ions. Increased usage of nCeO2 may raise its content in the environment, i.e. accumulation in water, air and soil. In many studies nCeO2 was coated with different polymers, but data on the effects of coated nCeO2 on crop species are scarce.
In this study, wheat and pea seeds were exposed to 5 day treatment with 200 mg/L uncoated and glucose-, levan- and pullulan-coated nCeO2 during germination. After three weeks of seedlings growth in hydroponics, phenolic profile in shoots was examined.
HPLC profiles showed unchanged qualitative composition (type and number of phenolics) in both tested plants. Among 5 identified phenolics, changes in peak areas were observed only in the most dominant phenolic-vicenin 1 in wheat, and in 3 phenolic compounds in pea. Results indicate minor changes of plants’ phenolic metabolism.
