Evaluating the Antimicrobial Effects of Silver Nanoparticles Synthesized from Green Tea Extract

This study investigates the antimicrobial properties of silver nanoparticles (AgNPs) synthesized using green tea extract against common pathogenic bacteria. The biosynthesized nanoparticles were characterized using UV–Vis spectroscopy and scanning electron microscopy (SEM). Their efficacy was tested against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa. The green-synthesized AgNPs demonstrated significant antimicrobial activity, with maximum inhibition observed against S. aureus. These findings suggest the potential of plant-mediated nanoparticles as alternative antimicrobial agents.
