Phytogenic Silver Nanoparticles Using Heteropogon Contortus Leaf Extracts And Its Anti-Bacterial Activity

Abstract

Nanoparticles are being viewed as fundamental building blocks of nanotechnology. Biosynthesis of nanoparticles by plant extracts is currently under exploitation. In the current study, Heteropogon contortus was used for extra cellular synthesis of metallic silver nanoparticles. Stable silver nanoparticles were formed by treating aqueous solution of AgNO₃ with the plant leaf extract as reducing agent at room temperature. UV-Visible spectroscopy was utilized to monitor the formation of silver nanoparticles. Synthesized Ag nanoparticles were effective anti-bacterial agent’s against Bacillus subtilis, Staphylococcus aureus, Proteus vulgare and Klebsiella pneumoniae. Our proposed work offers an enviro-friendly method for phytogenic silver nanoparticles production.
