Facile Green Synthesis and Biological Activities of Silver Nanoparticles using Coldenia procumbens Linn.

摘要

The facile green synthesis of silver nanoparticles is finding an imperative use in different fields due to their potential applications. The present study is focused on the green synthesis of silver nanoparticles from Coldenia procumbens Linn., in an eco-friendly way in order to reduce the toxicity from chemical methods. The zeta potential, size of the silver nanoparticles was measured and the characterization was done from UV-visible spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy. The disc diffusion method has used to evaluate the antimicrobial efficacy of synthesized nanoparticles with different bacterial pathogens and the antioxidant capability of silver nanoparticles was tested and has shown significant DPPH radical scavenging activity.
