Green synthesis of stable silver nanoparticles using Euphorbia milii extract and study of its antimicrobial activity against Escherichia coli


Author(s): B Pokhrel, JJ Nilling, Tomi Ete and Ajay Bharti

Abstract: Single step green synthesis of stable silver nanoparticles from silver nitrate solution has been successfully carried out with the help of natural reducing agent from the extract of Euphorbia milii plant by simple heating at 900 C. The nanoparticles were characterized using UV-visible spectroscopy and transmission electron microscopy. The diameters of the almost spherical nanoparticles were found in the range of 6-50 nm with average particle size of nearly 23 nm. Zone inhibition test for the study of antimicrobial activity of silver nanoparticles was conducted against the strain of E.coli pathogen and significant inhibition of the bacterial strain was observed.
