ANTIBACTERIAL ACTIVITY OF GREEN BIOSYNTHESIS OF MAGNETIC IORN OXIDE NANOPARTICLE OF MURRAYA EXOTICA L. AQUEOUS EXTRACT AGAINST HUMAN PATHOGENS

The green synthesis of magnetic iron oxide nanoparticles is a convenient, economical, rapid and eco-friendly method compared to physical and chemical synthesis methods. In the present study iron oxide nanoparticles synthesized by Murraya exotica L. leaves extract. The formation of iron oxide nanoparticles was confirmed by the colour change and further characterized by UV-Visible Spectroscopy, FT-IR analysis, DLS and XRD. The morphology and the size of nanoparticles were analyzed by SEM and HR - TEM analysis. The antibacterial efficacy of synthesized iron oxide nanoparticles exhibited considerable activity against the tested human pathogens. Our study shows that green synthesized iron oxide nanoparticles can be a good source for alternative therapy of bacterial diseases. Key words: Green synthesis, iron oxide, nanoparticles, Murraya exotica, antibacterial efficacy
