Study of the Antioxidant Efficacy of Laboratory andcommertial Silver Nanoparticles intercalated with ZnO

Abstract

The preparation of silver nanoparticles has been studied in two ways (industrial and laboratory) and the prepared silver nano composites (industrial and laboratory) have been diagnosed with XRD, FTIR and AFM techniques. As the average sizes of the nanocomposites prepared were obtained with (62.41 nm) for industrial nano silver and (45.36 nm) for laboratory silver nanoparticles, the antioxidant activity was measured by the method of scavenging free radicals DPPH by comparison with a standard solution of ascorbic acid. The experimental results indicated that the antioxidant activity To oxidize silver nanoparticles more than industrial silver,
