Versatile Tool

The green synthesis is the versatile tool to produce the nano scale materials. The present study deals with the synthesis of gold nanoparticles using the Cassia auriculata flower extract. The complete reduction of gold ions was observed after 45 min of reaction under stirrer condition. The colour changes in reaction mixture (dark red colour) was observed during the reaction period because of the formation of gold nanoparticles in the reaction mixture enables to produce particular colour due to their specific properties (Surface Plasmon Resonance). The formation of gold nanoparticles was confirmed using UV visible spectroscopy, the size of the nanoparticles measured by using particle size analyzer. The morphology of the poly dispersed gold nanoparticles was studied using TEM, This green synthesis method is cost effective; and eco friendly technique to produce large scale production of Nanomaterials
