10.22376/ijpbs.2019.10.1.p1-12 Volume 5 Issue 1 2014 (January - March) In this study, the biosynthesis of silver nanoparticles was carried out by using lessThan i greaterThan Psoralea lessThan /i greaterThan lessThan i greaterThan corylifolia lessThan /i greaterThan L. (family Leguminosae) as reducing agent. As per our knowledge, this is the first report where lessThan i greaterThan Psoralea lessThan /i greaterThan lessThan i greaterThan corylifolia lessThan /i greaterThan seed extract was found to be suitable for the green synthesis of silver nanoparticles. Synthesis of silver nanoparticles was confirmed on the basis of UV-Vis Spectrometer which showed a peak between 400 nm to 440 nm. The synthesized silver nanoparticles were characterized by X-ray diffraction analysis (XRD), Field emission scanning electron microscopy (FE-SEM), and particles size distribution analysis. The biosynthesized silver nanoparticles have been evaluated in vitro for antimicrobial activities and found to have higher antimicrobial activities. SUNITA D. DANAI-TAMBHALE AND PARAG V.
