Ecofriendly Green Synthesis of Iron Oxide Nanoparticles Using citrus sinensis

Abstract

Green protocols being eco-friendly and cost effective approach are most widely used for the production of iron oxide nanoparticles using plant-mediated extract of Citrus Sinensis, moreoverbiosynthesized iron oxide (FeO) nanoparticles shows better antibacterial activity.Green synthesis of nanoparticles has been broadly studied from the past few years because of their different features and potential applications in various fields. The successful biosynthesis of iron oxide nanoparticles was confirmed and characterized using UV-Visible spectroscopy, Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR) analysis and Zeta sizer. Antibacterial effect of biologically produced iron oxide nanoparticles was tested against Gram-negative bacteria (Escherichia coli) and Gram-positive bacteria (Macrococus). These results exhibited that iron oxide nanoparticles have high antibacterial potential as these nanoparticles showed significant zone of inhibition against bacteria strains. The proposed green synthesis of iron oxide nanoparticles (NPs) from Citrus Sinensis can be strongly recommended as a potential method for industrial application.
