Plant Extract as Green Synthesis Agent for Silver Nanoparticle Synthesis and Evaluation of Their Antibacterial Activit

Silver nanoparticles (AgNPs) have gained significant attention due to their eco-friendly synthesisand remarkable antibacterial properties. In this study, AgNPs were synthesized with a silver nitrate solutionand bio-reducing agents extracted from neem (Azadirachta indica) leaves through a simple and cost-effectivewater bath treatment method. The synthesized nanoparticles were characterized using UV-Visible spectroscopyand X-ray diffraction (XRD) analysis. The antibacterial activity of the AgNPs was evaluated againstStaphylococcus aureus using standard antimicrobial assays. The results demonstrated significant antibacterialefficiency. This eco-friendly approach provides a sustainable and green alternative for nanoparticle synthesis,reducing the hazardous environmental impact associated with conventional chemical methods.
