BIOSYNTHESIS OF SILVER NANOPARTICLES USING MALUS DOMESTICA LEAF EXTRACT AND ITS BIOLOGICAL APPLICATIONS AGAINST HUMAN PATHOGENS

The silver nanoparticles were synthesized by employing a green Malus domestica leaf extract assisted process. The synthesized nanoparticles were analyzed using the instruments FTIR, UV-Vis, PXRD, AFM and SEM with EDS for chemical, structural and morphological studies. It is observed that the phytochemicals present in the leaf extract are responsible for the stable nature of synthesized nanoparticles. The green synthesized silver nanoparticles have shown effective radical scavenging as well as antibacterial activities. From our current findings that the synthesized nanoparticles showing growth inhibitory activities against both gram positive and gram negative pathogenic bacteria, we can say that the synthesized nanoparticles can be used in medicine as the therapeutic agents.
