Green Synthesis and Characterization of Nickel Nanoparticles using Aqueous Extract of Moringa oleifera Flower

Abstract

An attempt has been made in this work to green synthesize nickel nanoparticles using the aqueous flower extract of Moringa oleifera, a common plant in which all parts are edible and rich in iron content, through the biosynthesis method. The synthesized Moringa oleifera flower extract nanorods were characterized by UV–Vis. spectroscopy, Fourier Transform Infrared spectroscopy, X-Ray Diffraction analysis and Transmission Electron Microscopy. In addition, the antimicrobial activity of the nanorods was evaluated. The nanorods were found to be crystalline in nature with rod-like structures having a mean particle size of 35 nm.
