Synthesis of Silver Nanoparticles Using the Leaf Extract of Vitex negundo and Its Anti-Bacterial Effect

摘要

Silver nanoparticles are known to have antimicrobial activity. The green synthesis method of nanoparticle synthesis is one of the most cost effective and eco friendly method. The present study is based on the synthesis of silver nanoparticles by the self reduction of silver nitrate by the leaf extracts of Vitex negundo which is one of the novel methods used in developing nanoparticles. The characterization of the particle was done by UV-Vis spectrophotometer, Fourier Transform Infra Red Spectroscopy, X-ray Diffraction analysis and the size of the synthesized nanoparticle was analyzed in the Scanning Electron Microscopy. The size of the particle was found to be 56 nm. The obtained silver nanoparticles showed anti-microbial activity against E.coli and Klebsiella pneumonia.
