Green Synthesis and Characterization of Gold Nanoparticles from Erythrina Variegate Plant Extract

Abstract

To develop a reliable, eco-friendly and easy process for the synthesis of gold nanoparticles using leave extracts of medicinal plant “Erythrina Variegate”. The use of plant material not only makes the process eco-friendly but also the abundance makes it more economical. In the present research program, cost effective and environment friendly gold nanoparticles were synthesized using the Erythrina Variegateleave extract as the reducing agent. The biosynthesized gold nanoparticles were analysed by UV- Vis,FTIR, XRD, EDX, SEM and TEM. The broadening of peaks in the XRD patterns was attributed to particle size effects. On whole, the aunps obtained by the biogenic syntheses have potential biological and medical applications. UV-visible spectrum of the aqueous medium containing gold nanoparticles showed a peak around 537nm. FT-IR analysis confirmed reduction of Au3+ ions to Au0 ions in synthesized gold nanoparticles. The leave extract of “Erythrina Variegate” quickly reduces Au3+ to Au0 and enhances the synthesis of gold nanoparticles.
