Green Synthesis of Gold Nanoparticle using Nutmeg Fruit Extract

Nanotechnology is an interdisciplinary branch of science which deals with the synthesis, processing and application of nanomaterials. Nanomaterials are particles in the range of 1-100nm. Researchers have keen interest in finding a green synthetic method for the production of gold nanoparticles due to its distinctive properties and technological application. In this article, the biosynthesis of gold nanoparticle by chloroauric acid using nutmeg (Myristica fragrans) fruit extract was reported. This method is simple, low cost and environment friendly. Nutmeg fruit extract acts as the reducing and stabilizing agent. Water is used as the solvent and chloroauric acid as the metal precursor. This method is a chemical reduction method by bottom-up approach. Different concentrations of nutmeg fruit extract were prepared for this experiment. The reduction of Au (III) to Au (0) was confirmed by UV-Visible spectroscopy. The characteristic strong absorption band at 530nm reveals the presence of gold nanoparticle.
