Abstract: Background: Nanoparticles have great importance due to their wide range of applications in various fields such as biology, pharmaceutical, biotechnology, medical, physics, chemistry, food industry, and textile industry, etc. Green synthesis is the safe and eco-friendly method to synthesize silver nanoparticles, these nanoparticles were found to have antibacterial efficacy. Aim/objective: The present study aimed to the synthesis of stable silver nanoparticles (AgNPs) using aqueous stem bark extract of Ficus mollis Vahl. a traditional medicinal tree taxon. Methods: The synthesized nanoparticles were characterized by using UV-Vis spectroscopy with a scan range of 190-750 nm, FT-IR spectroscopy, XRD (X-ray diffraction pattern), SEM with EDAX (Scanning Electron Microscope), and TEM (Transmission Electron Microscope). Results: The colour change from light brown to extreme essence brown was observed based on the peak at 438 nm obtained from UV-Vis spectroscopic analysis. FT-IR spectroscopic data confirmed that alcohol and amine of stem bark aqueous extract were responsible for the capping and stabilization of the AgNPs. Crystallographic studies through XRD indicated the AgNPs are crystalline. The TEM reveals that nanoparticles are spherical and contain a size range from 8.06 to 18.20 nm. EDAX patterns of synthesized AgNPs showed a 04.26 weight percentage of Ag metal in the sample indicate the purity of the reaction mixture. The anti-bacterial efficacy of synthesized AgNPs showed toxicity on four selected (two gram-negative and two-gram positives) bacteria. Conclusion: These studies revealed that the selected traditional medicinal plant contains the potentiality towards the synthesis of tiny-sized nanoparticles and can inhibit the growth of bacterial strains.
