Effect of Physical Parameters on Green Synthesis of Gold Nanoparticles using Zea Mays Extract

Author information unavailable

Abstract

Gold nanoparticles (AuNPs) were produced by green synthesis method by utilization of Zea Mays Extract as the reducing and stabilizing solution. Selected parameters like Time, Temperature, pH, Light and Concentration effects on the preparation of gold nanoparticles was analyzed by UV- Visible Spectroscopy (UV-Vis.). The size was measured through Dynamic Light Scattering (DLS) and also confirmed by Transmission electron microscopy (TEM) techniques, it is also observed that all the reaction time, Temperature, Concentration and reaction time are very essential parameters which should be noticed with high precession during the synthesis of Gold nanoparticles.
