Authors(2) :-P. Mohanapriya, R. Sathiyapriya

In the present study, simple, low cost and ecofriendly method is described for the synthesis of gold nanoparticles (GNPs) using fresh water Spirogyra sp. algae. The formations of gold nanoparticles were characterized by the peak obtained at 535.0 nm in UV- spectroscopy and further confirmed by Scanning electron microscope (SEM) analysis of size range from 40-50 nm. Then antioxidant study was carried out using ascorbic acid as standard and free radical scavenging activity of the GNPs was determined with hydrogen peroxide.
