Bioreduction of silver nanoparticles characterizations and their antimicrobial activity

Abstract

In this investigation we report the bioreduction of silver nitrate to silver nanoparticles using the leaves aqueous extract of Alangium lamarckii. The silver nanoparticles were characterized by UVvis spectrophotometer, scanning electron microscope (SEM), DLS-Size and zeta potential analysis showed that the synthesized silver nanoparticles are varied from 60 - 70 nm and have the spherical shape. Further the prospect of protein as a stabilizing material in silver nanoparticles is shown by FTIR analysis and the XRD examination confirms monocrystalline phase of silver with FCC crystal structure. The antimicrobial activity of Ag nanoparticles was investigated against some pathogens. In these assessments, silver nanoparticles (AgNP) can stop microbial growth and even kill microbes, from now confirmed their antimicrobial importance.
