Green synthesis and optimization of gold and silver nanoparticles from Colocasia Esculenta root extract with their potential pharmacological applications
by Dr. reshma, 01 Nov 2020

The wide range of applications of silver and gold nanoparticles in various fields like nanomedicine, chemical sensing, and electronics has become one of the main reasons for an emerging popularity for them. The utilization of lethal reagents and toxic solvents is primarily involved in the contemporary techniques of nanoparticles. The need of the hour is to augment novel mechanisms that synthesize gold and silver nanoparticles by making use of ecologically safe reagents and solvents. The swift and efficient green synthesis of gold and silver nanoparticles by using root extract of Colocasia Esculenta customarily known as Arvi can be reported. The technique used to scrutinize and monitor the quantitative formation of silver and gold nanoparticles is UV-Vis absorption spectroscopy. The UV-Vis absorption spectroscopy (UV/Vis), Field Emission Scanning electron microscopy (FESEM), Transmission Electron Microscopy (TEM) and X-ray diffraction (XRD) are the techniques which were used to observe the primary characteristics of the attained gold and silver nanoparticles. Surface Plasmon Resonance (SPR) was exhibited by UV/Vis spectrum for gold and silver nanoparticles at 540 and 420 nanometers respectively. The average diameter of the gold and silver nanoparticles which was prepared in the solution was 85nm and 105 nm respectively. Synthesized particles reflected a spherical shape. Besides being biological systems, the whole synthesis process is cost effective as well. Also, the influence of root extract and the concentration of metal ion was also deliberated.
