Abstract: The field of nanotechnology is one of the most active researches nowadays in modern material science and technology. Eco-friendly methods of green mediated synthesis of nanoparticles are the present research in the limb of nanotechnology. The aim of the present study was to synthesize silver nanoparticles from 1mM AgNO3 solution through aqueous leaf extract of Ocimum sanctum reducing as well as capping agent. Silver nanoparticle which has promising antimicrobial properties. Green synthesised silver nanoparticles showed zone of inhibition against isolated gram positive (Bacillus species and Staphylococcus species) and gram negative (Pseudomonas aeruginosa and Escherichia coli) bacterial and fungal strain (Fusarium species, Penicillium species and Aspergillus species). The nanoparticles were characterized by Scanning Electron Microscopy. Different reducing and capping agent was characterised by various phytochemical tests.
