Biogenic synthesis and characterization of silver nanoparticles using strobilanthes crispus and in-vitro determination of antioxidant activity

The aim of this study was to determine the antioxidant activity of biogenic synthesized silver nanoparticles (AgNPs) using Strobilanthes crispus. The formation of AgNPs using S.crispus was confirmed by using characterization techniques included UV-Vis spectrum, FTIR, XRD, SEM and EDS analysis. Sunli...
