Green synthesis of Gold Nanoparticles and their characterization

Abstract

Biocompatible gold nanoparticles have gained considerable attention in recent years for potential applications in different fields such as medicine, catalysis, electronics and biotechnology. This work is aimed at exploring the green synthesis of gold nanoparticles using cumin and fennel seeds as simple, non-toxic, eco-friendly ‘green materials’. The growth of nanoparticles was monitored by UV-Vis spectrophotometer. The UV-Vis spectrum of cumin and fennel-gold nanoparticles showed a peak in the region of 535and 540 nm respectively corresponding to the surface Plasmon resonance band (SPR) of gold nanoparticles.
