Abstract

Researchers have shown considerable interest in developing a green synthesis method for silver nanoparticles (AgNPs) with targeted antimicrobial properties. In this study, AgNPs were successfully synthesized using a green approach and characterized using UV-Vis spectroscopy, SEM, and FTIR analysis. At a silver nitrate (AgNO3) concentration of 0.1 mM, stable AgNPs were produced, confirmed by a color change from yellow to brown and spectrophotometric analysis showing an optical density peak at 417 nm, indicative of plasmon absorbance. SEM analysis revealed the morphology and size of the AgNPs, while FTIR spectroscopy provided insight into their structural properties. The synthesized AgNPs exhibited potent antibacterial activity against both Gram-positive and Gram-negative bacteria, suggesting their potential as effective antimicrobial agents.
