Abstract: Nanoparticles are microscopic objects ranging in size from 1 to 100 nm. The distinctive properties of nanoparticles are their size, morphology and bioactivity. Metallic nanoparticles make up to 90% of all used nanomaterials. This paper presents a new approach to obtaining silver nanoparticles by chemical reduction of silver cations in the presence of biopolymer reductants and stabilizers sodium alginate and sodium carboxymethylcellulose. The obtained silver nanoparticles were used to cultivate the biomass of Chlorella vulgaris. The results of the experimental studies showed the environmental safety and bioactivity of the obtained nanoparticles for the growth of microalgae. The most pronounced stimulating effect was found for silver nanoparticles obtained in the presence of the biopolymer sodium carboxymethylcellulose.
Keywords: chlorella vulgaris, silver nanoparticles, biopolymer, sodium alginate, sodium carboxymethylcellulose
