AB  - Nanočestice cerijum-oksida (nCeO2) su nanomaterijal popularan zbog izmene Ce3+ i Ce4+ oksidacionih stanja. Međutim, niska stabilnost i taloženje nCeO2 u vodenoj sredini predstavljaju ograničenje njihovoj raznovrsnoj primeni.U prvom delu teze su sintetisane nCeO2 samopropagirajućom metodom na sobnoj temperaturi. Nanočestice su stabilizovane oblaganjem glukozom, levanom ili pululanom zbog visoke hidrosolubilnosti i biokompatibilnosti. Pululan je prvi put korišćen za oblaganje nCeO2. Nanočestice su oblagane tokom i nakon sinteze variranjem različitih uslova (vreme oblaganja, temperatura i količina materijala za oblaganje).U drugom delu teze neobložene i glukozom, levanom ili pululanom obložene (G-, L- ili P-CeO2) nCeO2 su okarakterisane skenirajućom i transmisionom elektronskom mikroskopijom, rendgenskom difrakcijom, infracrvenom spektroskopijom sa Furijeovom transformacijom, rendgenskom fotoelektronskom spektroskopijom, nuklearnom magnetnom rezonancom, metodom dinamičkog rasejanja svetlosti i turbidimetrijom. nCeO2, oblagane ugljenim hidratima nakon sinteze tokom 6 h, podvrgnute su daljem ispitivanju.U trećem delu teze ispitani su biološki uticaji neobloženih i obloženih nanočestica na četiri biljne vrste tretiranjem tokom klijanja (3-5 dana) i rastenja (3 nedelje). Testiran je uticaj oblaganja na usvajanje nanočestica, klijanje i razvoj biljaka, kao i parametre sekundarnog metabolizma (ukupni i pojedinačni fenoli i ukupna antioksidativna aktivnost). Detektovana su poluisparljiva jedinjenja u pšenici i grašku sveobuhvatnom dvodimenzionalnom gasnom hromatografijom. Akutna toksičnost nanočestica je testirana na bakteriji (Vibrio fischeri), slatkovodnom račiću (Daphnia magna) i zebrici (Danio rerio).

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 (nCeO2) on plants are contradictory due to their positive and negative effects on plants. Surface modification may affect the interaction of nCeO2 with the environment, and hence its availability to plants. In this study, the uncoated and glucose-, levan-, and pullulan-coated nCeO2 were synthesized and characterized. The aim was to determine whether nontoxic carbohydrates alter the effect of nCeO2 on the seed germination, plant growth, and metabolism of wheat and pea. We applied 200 mgL-1 of nCeO2 on plants during germination (Ger treatment) or three week-growth (Gro treatment) in hydroponics. The plant response to nCeO2 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 nCeO2 had the strongest and positive impact on tested plants. Wheat showed higher sensitivity to all treatments.

AB  - Cerium oxide (CeO2) nanoparticles (CONPs) are interesting biomaterials with various applications in biomedicine, cosmetics and the pharmaceutical industry, but with limited practical application because of their low stability in aqueous media. The aim of this study was to obtain CONPs with increased stability by coating the particles. Microbial exopolysaccharides (levan, pullulan) and glucose were used to prepare CONPs under different synthesis conditions. Coating was attempted by adding the carbohydrates during (direct coating) or after (subsequent coating) the synthesis of CONPs. The obtained nanoparticles were characterized by X-Ray diffraction analysis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The suspension stability of the uncoated and coated CONPs in aqueous media was evaluated by measuring the hydrodynamic size, zeta potential and turbidity. The FT-IR spectra revealed the differences between coated CONPs and showed the success of subsequent coating with carbohydrates. Coating with carbohydrates improved the stability the CONP suspension by decreasing the size of aggregated particles. The suspensions of levan- and glucose-coated CONPs had the best stability. In this study, CONPs were prepared using non-toxic materials, which were completely environmentally friendly. The obtained results open new horizons for CONP synthesis, improving their biological applications.

Coating was attempted by adding the carbohydrates during (direct coating) or after (subsequent coating) the synthesis of CONPs. The obtained nanoparticles were characterized by X-Ray diffraction analysis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The suspension stability of the uncoated and coated CONPs in aqueous media was evaluated by measuring the hydrodynamic size, zeta potential and turbidity. The FT-IR spectra revealed the differences between coated CONPs and showed the success of subsequent coating with carbohydrates. Coating with carbohydrates improved the stability the CONP suspension by decreasing the size of aggregated particles. The suspensions of levan- and glucose-coated CONPs had the best stability. In this study, CONPs were prepared using non-toxic materials, which were completely environmentally friendly. The obtained results open new horizons for CONP synthesis, improving their biological applications.",
