Green Synthesis and Antibacterial Activity of Silver Nanoparticles(AgNPs) using Psoraleacorylifolia Seed Extract

Abstract

Silver nanoparticles using psoraleacorylifolia seed extract has been synthesized by green synthesized method. The size of the nanoparticle was found to be 38nm by powder X-ray diffraction method. From the FTIR spectrum the vibrational frequency at 641cm-1confirms the bioreduction of silver nitrate into Ag+ ion and spherical morphology of silver nanoparticles were identified using SEM and TEM analysis. The optical properties were analysed and cut off wavelength at 429nm was found using UV-Vis spectrum. The surface potential of the green synthesized nanoparticles was calculatedby Zeta potential method. Biosynthesized silver nanoparticles were further evaluated for their potential antibacterial activity and it may be used as nanomedicine for skin diseases.
