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.

“…The peak at 2365 cm −1 corresponds to –CH group, and peaks at 3006, 3130 cm −1 correspond to –OH group 31 . The characteristic peaks observed for Fe 3 O 4 NPs are consistent with the reported literature, confirming the phase purity of Fe 3 O 4 NPs 32,33 …”

Green synthesis of biocompatible Fe3O4 magnetic nanoparticles using Citrus Sinensis peels extract for their biological activities and magnetic-hyperthermia applications

“…According to VSM measurements, the M S value of magnetic SPIONs nanocomposite is 102 emu, which relates to non-magnetic shells excessing in the nanocomposite 59 , 60 . The decreasing nanocrystallite size from XRD data, growing lattice strain, and the presence of Fe 2+ ions in the system 61 , 62 , where increasing anisotropy is a constant value, may support the increasing coercivity (H c ) value of 286emu. The UV–Visible spectra for SPIONs is appropriate surface plasmon resonance (SPR) by greater band strength at 259 nm was used to demonstrate how Citrus sinensis peel extract reduces the SPIONs.…”
