The methods like bio-green are beneficial over chemical and physical methods due to biodegradable and cost-effective synthesis of nanoparticles. Current study was planned for green synthesis of silver nanoparticles (AgNPs) and their biological assessment. Methods: Methanolic extract of Carica papaya root prepared by maceration was used for the synthesis of AgNPs and confirmed by UVevisible spectroscopy. Further field emission scanning electron microscope (SEM) was used for the shape and size determination of the nanoparticles. The nanoparticles was spherical in shape having average particle size of 35 nm.. Green synthesized nanoparticles (AgNPs) showed the enhanced antioxidant properties compared to the crude extract..: Green synthesized AgNPs showed the improve the biological activities. Present study also support the importance of using bio-green method for the production of nanoparticles having the potential of anti-oxidant activity

key word Uv-Vs spectroscopy SEM, anti oxidant activity
