Abstract
Silver nanoparticles (AgNPs) due to biocompatibility, antibacterial action and its various applications in the field of electronics, optical, magnetic have attracted considerable attention. In this study silver nanoparticles were successfully produced from silver nitrate using leaves extracts of Murrayakoenigii, Moringaoleifera and Ocimum sanctum. The AgNPs were characterized using UV-visible spectroscopy at the wavelength of 300-600nm. The antibacterial activities against different pathogens (Escherichia coli, Staphylococcus aureus) were reported. The zone of inhibition was observed both in gram positive and gram negative bacterial strains. They were found to have considerable inhibitory action against the mentioned microorganisms.
