Abstract

Present study consists a simple and eco-friendly biosynthesis of silver nanoparticles using <i style="mso-bidi-font-style:normal">Sargassum longifolium</i> aqueous extract as reducing agent. Aqueous silver ions when exposed to seaweed extract were reduced and results in silver nanoparticles. Characterization of these silver nanoparticles were done using UV-Vis spectroscopy, Fourier Transform Infra red (FT-IR) spectroscopy, Scanning Electron Microscopy (SEM) and Energy Dispersive analysis X-ray (EDS) Spectrum. Cytotoxicity assay was done against Hep 2 cell line. The cytotoxicity analysis of the sample shows a direct dose-response relationship; cytotoxicity increased at higher concentrations.
