Synthesis of Silver Nanoparticles using Cinnamomum zeylanicum Bark Extract and its Antioxidant Activity

In this study, we report the synthesis of silver nanoparticles from cinnamon bark extract. The physical charactrization of these silver nanoparticles was verified using UV-visible spectroscopy, scanning electron microscopy, and powder X-ray diffraction. Size distribution of nanoparticles was in the range of 30 to 150 nm. The zeta potential was -32 mV, indicating dispersion ability. Superoxide anion radical scavenging assay showed 82% activity for silver nanoparticles derived from cinnamon bark extract.
