Abstract

Abstract: Green synthesis of CeO2 Nanoparticles (NPs) with small size and high stability paved the approach to recover and protect the environment by decreasing the use of toxic chemicals and eliminating biological risks in biomedical applications. Peel-mediated synthesis of CeO2 NPs is gaining more importance owing to its easiness and eco-friendliness. In this study, biosynthesis of CeO2 NPs using the fruit peel extract of punica granatum is reported. The synthesized CeO2 NPs are characterized by Powder X-ray Diffraction (PXRD), UV-Diffused Reflection Spectroscopy (UV-DRS), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-Ray Analysis (EDAX) and antimicrobial activity. The CeO2 NPs show more lethal activity towards gram +ve bacteria than towards gram –ve bacteria. Keywords: Biosynthesis, Optical properties, Antimicrobial activity.
