Synthesis and Evaluation of Antibacterial Activity of Silver Nanoparticles from Lantana Camara Leaf Extract

There were many work have been made based on the plant and its extract mediated synthesis of nanoparticles. Metal related nanoparticles are usually synthesized by wet chemical methods, where the chemicals used are quite often toxic and flammable. In this work, we describe a cost effective and environment friendly technique for green synthesis of silver nanoparticles from 1mM AgNO3 solution through the extract of Lantana camara leaf as it is acts as a reducing as well as capping agent. Nanoparticles were characterized using UV–Vis absorption spectroscopy and SEM analysis showed the average particle size range15-40nm with higher density polydispersed spherical in shape. The synthesized silver nanoparticles exhibited potential antibacterial activity against some bacteria such as Escherichia coli, Staphylococcus aureus and Bacillus subtilis represented respectively.
