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  - 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  - A glassy carbon electrode (GCE) was surface-modified with carbon quantum dots (CQDs) and applied for the effective enhancement of the electrochemical signal for dopamine and uric acid determination. CQDs were prepared from graphite by a green modification of the Hummers method. They were characterized by FTIR-ATR, XPS, solid-state NMR, fluorescence and Raman spectroscopies. TPD-MS analysis was applied to characterize the functionalization of the surface. The CQDs were assembled on the glassy carbon electrode by adsorption because of the large number of carboxy groups on their surface warrants effective adsorption. The modified GCE exhibits a sensitivity that is almost 10 times better than of the bare GCE. The lower limits of detection are 1.3 mu M for uric acid and 2.7 mu M for dopamine.

AB  - In this work carbon quantum dot (CQD) nanoparticles are synthesized from D-lactose using a hydrothermal method and then they are coated with polyethylene glycol (CQDs"PEG). These particles exhibit a monodisperse spherical morphology with an average particle size of similar to 4 nm. Nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopy showed the presence of the hydroxyl groups from the ethylene glycol molecules grafted onto the CQDs' surfaces, which confirms that PEG was covalently attached to the nanoparticles' surfaces. Fluorescence analysis demonstrates a shift in the emission at 495 nm after PEG coating. Modified carbon dots were introduced into thermo-responsive pNIPAM microgels. The resultant pNIPAM-CQDs"PEG hybrid system exhibits interesting fluorescence properties. Transmission electron microscopy (TEM), fluorescence microscopy, and energy-dispersive X-ray (EDX) spectroscopy confirm the incorporation of CQD particles into the microgels. Finally, dynamic light scattering (DLS) analysis confirms that further hybrid microgels based on pNIPAM are thermo-responsive, with a transition temperature similar to that of a system with an ionic component.
