Biosynthesis of silver nanoparticles (AgNPs) has been performed using various sources including plants and fungi. Sargassum swartzii is an alga that a vast spectrum biological activities predominantly found on the Indian coasts. In this study, AgNPs was biosynthesized S. evaluated for its antibacterial potency against Escherichia coli (ATCC 25922). The synthesized (NPs) were imaged TEM analyses to be spherical crystalline with size around 20–40 nm. Zeta sizing analysis revealed mean particle 40.4 XRD particles are nature average 54 used treating E. it cause considerable amount deterioration microbes when observed under AFM FE–SEM. study significant activity due extensive membrane damage.
