Phytochemical-assisted synthesis, optimization, and characterization of silver nanoparticles for antimicrobial activity.

ABSTRACT: The increasing prevalence of antimicrobial resistance (AMR) bacteria poses a major global health threat, compounded by the limited development of new antibiotics. To address this challenge, alternative strategies, including nanoparticle-based therapies, are being explored. This study investigates the antimicrobial properties of green-synthesized silver nanoparticles (AgNPs) derived from leaf extracts of Ocimum gratissimum (OG), Apium graveolens (AG), and Aloe arborescens (AA). These plant extracts act as reducing, capping, and stabilizing agents during the synthesis process. By controlling the reaction parameters, the synthesized AgNPs displayed surface plasmon resonance (SPR) peaks at 434, 427, and 435 nm for OG, AG, and AA, respectively, indicating successful nanopar
