OPTIMIZATION AND GREEN SYNTHESIS OF SILVER AND GOLD NANO-PARTICLES DERIVED FROM COLOCASIA ESCULENTA ROOT EXTRACT AND THEIR POTENTIAL PHARMACOLOGICAL APPLICATIONS.

The broad array of potential applications of silver and gold nano-particles in diverse fields is well-known. The utilization of lethal reagents is included in the contemporary procedures of synthesizing nanoparticles. In present times, there is necessity to augment novel mechanisms that lead to the synthesis of gold and silver nano-particles with the help of environmentally safe reagents. The reliable green synthesis of silver and gold nano-particles with the help of Colocasia esculenta root extract popularly called as Arvi, has been investigated here. The experimental procedure employed here to scrutinize and observe the synthesis of silver and gold nano-particles based on quantity is UV-Vis absorption spectroscopy. Surface Plasmon Resonance (SPR) was exhibited by UV/Vis spectrum for silver and gold nano-particles at 420 and 540 nanometers, respectively. The mean diameter of gold and silver nanoparticles synthesized in the solution was found to be 85 nm and 105 nm, respectively. The particles that were synthesized had a spherical shape.
