Glutathione promoted expeditious green synthesis of silver nanoparticles in water using microwaves

Abstract

Silver nanoparticles ranging from 5–10 nm in size have been synthesized under microwave irradiation conditions using glutathione, an absolutely benign antioxidant that serves as the reducing as well as capping agent in aqueous medium. This rapid protocol yields the nanoparticles within 30–60 s at a power level as low as 50 W. The effect of microwave power on the morphology of ensuing silver nanoparticles is investigated for this green and sustainable procedure which is adaptable for the synthesis of palladium, platinum and gold nanoparticles.
