BIOSYNTHESIS OF FUNCTIONALIZED GOLD NANOPARTICLES BY USING METHYL COMMATE C IN Scoparia dulcis LEAF EXTRACT AS REDUCING AGENT

Abstract

Biosynthesis of nanoparticles is studied extensively for its biocompatibility and its environmentally friendly nature. In the present study, the synthesis of gold nanoparticles is carried out using Scoparia dulcis aqueous leaf extract. The synthesis of gold nanoparticles is achieved at room temperature using aqueous leaf extract of Scoparia dulcis without the addition of an external agent. The color change was observed from light brown to ruby red indicating the formation of gold nanoparticles. The surface plasmon resonance band appeared at 542 nm in Ultra Violet-visible spectroscopy. In Fourier Transform Infrared spectroscopy the functional groups responsible for the reduction of chloroauric acid have been identified and in Transmission Electron Microscopy revealed that the gold nanoparticles were of 20-27 nm in size. Gas Chromatography-Mass Spectroscopy analysis and Nuclear Magnetic Resonance spectroscopy were used to assess the structure of the reducing agent.
