Silver has been known for many centuries worldwide for its antimicrobial activity. It can be prepared by various methods like physical, chemical and biological method. The biological method includes synthesis of silver nanoparticles from plant extract which is also known as green synthesis. In this study, synthesis of silver nanoparticles (AgNPs) has been performed using stem extract of Andrographis paniculata by reducing aqueous silver nitrate. The silver nanoparticles are characterized by Ultraviolet-Visible (UV-Vis) spectrophotometer. Antimicrobial activity of the silver nanoparticles has been demonstrated by agar well diffusion method and it was found to be effective against Pseudomonas aeruginosa, Bacillus sps, Micrococcus sps and Staphylococcus aureus isolated from the water sample.
