AN UNDEMANDING METHOD OF SYNTHESIS OF GOLD NANOPARTICLES USING PISONIA GRANDIS (R. Br.)

Gold nanoparticles were synthesized using the ethanol extract of leaves of Pisonia grandis by four physical techniques. The completion and formation of gold nanoparticles was analyzed by UV-visible spectroscopy. The synthesized gold nanoparticles were characterized by XRD, Scherrer's equation, SEM and FTIR analysis. The concentration, time and method of synthesis play a vital role in the kinetics of gold nanoparticles. The size and shape of nanogold that varied under different conditions explains the uniqueness of the method. The results of the study revealed the formation of gold nanoparticles of size ranging from 20 to 90 nm with 2 mg of extract and 1 mg of gold chloride at room temperature.
