Abstract: The aim of the study, a facile green approach to synthesize cobalt oxide nanoparticles by using Ficus religiosa leaf extract. The structural properties of the as - synthesized cobalt oxide nanoparticles were characterized by UV - Vis spectrophotometry, Fourier Transform Infrared (FT - IR), X - ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy dispersive X - ray spectroscopy (EDX) and Transmission Electron Microscopy (TEM). The antibacterial activity of the synthesized cobalt oxide nanoparticles when tested against two - gram positive bacteria and one - gram negative bacteria was evaluated and good results were obtained. The antifungal activity when tested against two fungi showed a very good result.
