Sažetak
Selenium (Se), essential natural trace element for various organisms recently attracts attention due to its potential beneficial effects in various fields, i.e. biomedicine, electronics and some other industrial applications. However, depending on the dose, it can exhibit adverse effects. Current opinion is that possible Se toxicity could be reduced if Se is applied in the form of nanoparticles. Despite this, little is known about possible negative impact of SeNPs on different organisms. In general, when addressing nanotoxicity, aquatic organisms are of major interest, since majority of engineered nanoparticles are released through waters into environment. In aquatic ecosystem microalgae acts as a major vector of Se transport from water to filter-feeders and other consumers. With the aim to determine safety of their use in cosmetic, food and pharmaceutical industry the influence of SeNPs on growth of freshwater microalgae Chlorella vulgaris and marine microalgae Dunaliella tertiolecta was compared to the influence of sodium selenite (NaSe2O3), inorganic Se source. SeNPs were synthesized by solution phase synthesis and characterized using powder X-ray diffraction. The hydrodynamic diameter and zeta potential of SeNPs were determined by dynamic and electrophoretic light scattering. Obtained results may contribute to the understanding of SeNPs toxicity and their biotechnological potential.
