- Abstract
Green synthesis of ZnO NPs with biological systems is becoming a growing field, especially in plant extracts nanotechnology. Biological reducing agents have been interpreted worldwide to lessen the impact of toxic chemicals applied in development of nanoparticles. In present research, work deals with green synthesis & characterization of ZnO NPs via Psidium guajava leaf extract, also to evaluate their antibacterial action against some selected bacteria. The preparation of ZnO NPs was attained via sol–gel assisted microwave irradiation process. The XRD pattern confirms the hexagonal phase of ZnO and crystalline size to be ~ 15.8 nm. FTIR analysis depicts the bio functional groups present in the surface of the ZnO nanoparticles, SEM predicts the size and morphology of the sample, and it shows rod-shaped surface. Then, the EDAX results showed the purity & elemental stoichiometry of the ZnO nanoparticles. Also, the UV was performed to investigate the optical nature of the prepared ZnO nanoparticles. Also, the antibacterial activity results revealed significantly inhibited both types of bacteria in higher concentrations. This study also suggests that green synthesized ZnO nanoparticles can an excellent antibacterial agent.
