“Characterization and Green Synthesis of Silver Nanoparticles from Plumeria Leaves Extracts: Study of Their Antibacterial Activity”.

Abstract

In the present work, the stable silver nanoparticles were synthesized by the bioreduction method. Aqueous leaf extracts of the Plumeria plant was used as reducing and as capping agent. The color change in reaction mixture from bright green to dark brown color was observed which indication of the reduction of Silver ions into Silver nanoparticles. The formation of silver nanoparticles (AgNPs) was characterized by UV-vis spectroscopy, FT-IR, SEM and XRD studies. The synthesized AgNPs exhibited good Antibacterial potential against gram positive and gram negative bacteria.
