摘要：

Present study reported a simple and green synthesis of silver nanoparticles (AgNPs) synthesized via rapid bio-reduction method. An aqueous extract of Givotia moluccana (G. moluccana) plant was serving as reducing and stabilizing agent. An aqueous extract was found to comprise significantly high amounts of secondary metabolites like phenolics, flavonoids, proteins and reducing sugars etc., which are responsible for reducing and capping agents. The synthesized AgNPs were characterized by UV-Visible spectroscopy, FTIR, XRD, FESEM and HRTEM with SAED pattern. Particle size distribution was measured by dynamic light scattering (DLS). Further, thermal analysis of nanoparticles were studied using TGA. Synthesized AgNPs exhibited antimicrobial activity against both gram positive and gram negative bacteria. (C) 2018 Elsevier B.V.
