This paper describing the synthesis of silver (Ag) nanoparticles from aqueous extract of fresh leaves of Lablab perpureus. This eco-friendly approach of synthesizing nanoparticles is green and cost-effective. The synthesized silver nanoparticles were characterized by various methods including ultraviolet–visible spectroscopy (UV–Vis), Fourier transform infrared (FTIR), Scanning electron microscopy (SEM), powder X-ray diffraction (XRD), and antimicrobial activity. UV–visible absorption of synthesized silver nanoparticles showed peak around 430 nm. The responsible biomolecules for the reduction of Ag0 from Ag+ and also the capping materials of silver nanoparticles were confirmed by FTIR . SEM image represents the morphology of the silver nanoparticles. The size of silver nanoparticles , crystalline nature and face centre cubic structure of nanoparticles confirmed by XRD. The biological activity of AgNPs against generally found bacteria and fungi was also analysed.
