Antibacterial and Antifungal Activity of Plant Mediated Iron Oxide Nanoparticles

In this study unexplored Albizia amara leaf extract was found to be capable in green synthesis of iron oxide nanoparticles and their characteristics were studied by using UV -Visible spectrometer, FT -IR, XRD, EDX, TEM and SAED pattern. Thus, biosynthesized iron oxide nanoparticles were naturally stabilised and in the size range of 100 -200 nm with average particle size 160 nm. The phytochemicals present in the leaf extract has a main role as reducing agent that assists to the eco -friendly synthesis of iron oxide nanoparticles with enhanced antibacterial and antifungal activities. Well diffusion procedure was trailed to evaluate the antibacterial potential of green synthesized iron oxide nanoparticles against Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus. The antifungal property of synthesized iron oxide nanoparticles was evaluated against Candida albicans and Aspergillus niger. The naturally stabilized iron oxide nanoparticles with herbal property can be used in various biological application.
