Abstract


Application of green methods to replace physical and chemical methods for synthesis of silver nanoparticles (AgNPs) has become necessary not only from economic aspect but especially due to its significant impact on ecosystem. The properties of biologically synthesized AgNPs using green algae Parachlorella kessleri (P. kessleri) and chemically prepared were investigated and compared. The UVvis analysis confirmed a high stability of biosynthesized AgNPs as well as chemically synthesized gelatin modified citrate-AgNPs. Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) revealed different sizes and shapes of AgNPs synthesized in different ways. Biosynthesized AgNPs have similar inhibitory antimicrobial activity as gelatin/sodium citrate–AgNPs.
