Abstract
Green synthesized nanoparticles are easily bio-available and eco-friendly in nature. Leaves of Dryopteris barbigera have medicinal properties. In this study, biogenic synthesis of silver nanoparticles (AgNPs) using D. barbigera leaf extract and their characterizations have been carried out. Surface plasmon spectra for AgNPs displayed absorbance peak with dark brown color at 418 nm. The synthesized AgNPs, were spherical with size ranging between 10.7-27.6 nm, lattice constant of 0.408 nm and crystallite size of 11.9 ± 2.9 nm. These AgNPs were biocompatible towards MCF-7 and A549 cancer cell lines and showed bactericidal effect against Staphylococcus aureus and Escherichia coli.
