Plant-mediated nanoparticle production is fast, simple, environmentally friendly, and inexpensive. This study synthesised silver nanoparticles using Clerodendrum bracteatum leaf extract. FT-IR, SEM, XRD, and Zeta potential were used to characterise silver nanoparticles. FT-IR was utilised to determine the functional groups responsible for reducing silver nitrate and capping agents in the leaf extract. Using Zeta potential, silver nanoparticles' stability was measured. Silver nanoparticles' 18.3 mV negative Zeta potential showed durability. Silver nanoparticles show antibacterial action against Staphylococcus aureus, Microc
