Aim: The present work pursues to synthesize Silver Nanoparticles (AgNPs) from aqueous leaf extract of Ficus mollis Vahl. and their microbial efficacy. Methods: The synthesized nanoparticles were characterized by using UV-Vis spectroscopy, FT-IR (Fourier transform infrared spectroscopy), XRD (X-ray diffraction), SEM (Scanning Electron Microscope) with EDAX, and TEM (Transmission Electron Microscope). Results: The colour change from light brown to dark brown is observed upon synthesis and the peak obtained at 444 nm with UV-Vis Surface Plasmon resonance (SPR) analysis confirmed the synthesis of nanoparticles are silver nanoparticles. FTIR analysis confirms that phenols and proteins of leaf extract are generally responsible for the capping and stabilization of green synthesized silver nanoparticles. Crystallographic analysis of XRD denotes, the AgNPs are crystalline. SEM revealed that the nanoparticles are spherical and their size ranges from 22.0 to 38.6 nm. EDAX pattern of biosynthesized nanoparticles showed a 1.44 weight percentage of Ag metal. TEM microscopic analysis divulges that the nanoparticles are spherical with sizes ranging from 8.36 to 23.11 nm. Antimicrobial analysis of the synthesized AgNPs exhibited a toxic effect on selected Bacteria. Conclusion: It denotes that aqueous leaf extract of Ficus mollis is preferable for synthesizing stable AgNPs and to formulate eminent antibacterial agents.
