Popis: In this present work, we report the antibacterial activity of Zinc Oxide (ZnO) and Copper Oxide (CuO) nanoparticles synthesized by environment friendly, cost effective, less complex, safe and stable method using Annona Muricata leaf extract as reducing and stabilizing agent without adding any surfactants. Synthesized metal oxide nanoparticles were characterized by X-Ray Diffraction, Fourier Transform Infrared Spectroscopy and Scanning Electron Microscope. X-Ray Diffraction results revealed that the biosynthesized ZnO and CuO nanoparticles were crystalline in nature with higher purity. The bacterial effect of ZnO and CuO nanoparticles were tested on both gram positive and gram negative bacteria. The results indicate gram positive bacteria shows greater sensitivity to ZnO nanoparticles whereas gram negative bacteria are more sensitive to CuO nanoparticles.
