Abstract
In this study, eco-friendly synthesis of silver nano particles was achieved by a novel, facile route using Azolla caroliniana extract which act as a capping as well as reducing agent. Different synthetic parameters and the optical properties of the synthesized AgNPs was also studied. The characterization of synthesized AgNPs was carried out by Ultraviolet–Visible (UV–Vis) spectroscopy, Fourier Transform Infrared spectroscopy (FTIR), X-ray Diffraction studies (XRD), and Transmission Electron Microscopy (TEM). TEM studies verified that the AgNPs formed have crystalline nature and spherical shape with an average diameter of 23 nm. The cyclic voltammetry profile of AgNPs modified electrode in NaOH depicted prominent redox peaks evidencing an impressive electrochemical response. The AgNPs shows high catalytic activity towards reduction of Crystal Violet and Fuchine which are highly polluting organic compounds. In addition to that the prepared AgNPs exhibited strong antibacterial activity against the tested microbes and also exhibits in vitro cytotoxicity against lymphoma ascites cells.
