Antibacterial study of silver nanoparticles synthesized using Strychnos potatorum(linn)-Green synthesis method

The production of nanoparticles is a fundamental process in nanotechnology research. Silver nanoparticles has tremendous application in medicine, optoelectronics, and energy. The bottom-up approach of nanoparticle production by green synthesis method is ecologically friendly, where the reaction is catalyzed by Phyto molecules. This process is viewed as less harmful and alternative to more extensive physical and chemical treatments. Our work describes a simple, fast, and eco-friendly approach for the production of silver nanoparticles (AgNPs) using Strychnos potatorum(linn) seed extract. The synthesized AgNPs were characterized using different techniques. The maximum absorption peak due to surface plasma resonance (SPR) of AgNPs is conformed at 423 nm. The Phyto chemicals present in the solution is confirmed using FTIR which is responsible for the reduction and stabilization of nanoparticles. The crystallite size of the nanoparticles is calculated as 32 nm from XRD data. From the SEM micrograph, the particle size is found to be ti 130 nm. Antibacterial activity against Staphylococcus aureus, Klebsiella pneumonia and Escherichia coli were studied and the maximum inhibition zone is reported.Copyright (c) 2022 Elsevier Ltd.
