Present study reports the biogenesis of silver nanoparticles from the leaves of Cardiospermum halicacabum L. and their characterization. C. halicacabum has been used in traditional medicines but so far it has not been tested for synthesis of silver nanoparticles (AgNPs). The aqueous silver ions exposed to the herbal extract, which were reduced and the nanoparticles were synthesized. The presence of nanoparticles was confirmed by the formation of brown color of the reaction mixture. The brown color was observed after 25 minutes. The silver nanoparticules qualitatively characterized by UV-Visible spectrophotometer. A sharp peak was observed in between 422nm to 447nm indicates formation of silver nanoparticles.
