A Biological Approach of Silver (Ag) Nanoparticles Synthesis Using Leaf Extract of Adhatoda Vasica

Dr. K. Vinoth Kumar, Dr. C. Udayasoorian

Abstract :

The present study deals with the biosynthesis of silver nanoparticles using the leaf extract of medicinal plant Adhatoda vasica. The complete reduction of silver ions was observed after 48 h of reaction at 300 C under shaking condition. The colour changes in reaction mixture was observed during the incubation period, because of the formation of silver nanoparticles in the reaction mixture enables to produce particular colour due to their specific properties (Surface Plasmon Resonance). The XRD pattern thus clearly shows that the silver nanoparticles are crystalline in nature. The synthesized silver nanoparticles were predominately spherical in shape, polydispersed and average particles size of 42 nm.
