Abstract: In nanotechnology, the plant mediated synthesis of nanoparticles has terrific application in biomedicine due to its novel properties and its eco-friendly nature. The present study deals with the biosynthesis of stable silver nanoparticles (SNPs) from leaf aqueous extract of Sophora interrupta an Endemic species of Seshachalam hill ranges of Tirumala. The synthesized nanoparticles are characterized by UV–VIS spectroscopy, Zeta potential, FTIR, XRD, with TEM and EDAX. Colour change, Observed from Gray to brown indicates the formation of nanoparticles and UV–VIS surface plasmonresonance spectroscopy observed at 442 nm further confirmed the synthesized nanoparticles as SNPs. FTIR spectroscopic studies confirm that phenols and proteins of leaf extract is mainly responsible for capping and stabilization of synthesized SNPs. The XRD data shows crystalline nature of nanoparticles and EDAX measurements reveal the13.56% percentage presence of Ag metal. Zeta potential at -19.7mV, negitive value indicates the high stability of Nanoparticles. TEM microscopic analysis revealed that the size of synthesized SNPs ranging from 5 to 50 nm with spherical shape. Further, the antimicrobial studies of synthesized SNPs show high activity towards different bacterial isolates.
