Nanotechnology is a branch of science that deals with nano-scale particles. Currently, nanotechnology in medicine has developed into something that’s making it possible to incorporate nanoparticles into medical appliances, boosting the treatment's effectiveness. The present study deals with the cost-effective green synthesis of silver nanoparticles using the leaf extract of Senna occidentalis, an important medicinal plant. The synthesized AgNPs were characterized by UV-Vis spectrophotometer, the functional groups were confirmed by FTIR, and size and shape were determined by scanning electron microscopy. The silver nanoparticles exhibited diverse biological applications: antibacterial, antifungal, antiviral, and larvicidal properties. The present work is evident that the silver nanoparticles possess good antibacterial activity against gram-positive and gram-negative bacteria, antifungal activity on A. niger, antiviral activity on Sesbania mosaic virus. The AgNPs could be used as therapeutic agents to treat microbial diseases for modern agricultural and medical sectors.
