Facile synthesis of silver chloride nanoparticles using marine alga and its antibacterial efficacy

Spectrochim Acta A Mol Biomol Spectrosc. 2014:120:416-20. doi: 10.1016/j.saa.2013.10.044. Epub 2013 Oct 19.

Abstract

Exploitation of advancements in antimicrobial agent synthesis assisted by nanomaterials has received considerable attention in the recent years. Based on this, an eco-friendly approach for the synthesis of silver chloride nanoparticles (AgClNPs) using aqueous extract of Sargassum plagiophyllum is emphasized. UV-vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), high resolution transmission electron microscopy (HR-TEM), field emission scanning electron microscopy (FESEM) were used to characterize the formation of AgClNPs. X-ray diffraction (XRD) patterns clearly illustrate the presence of AgClNPs. The synthesized AgClNPs were tested for its antibacterial activity and it was found to cause considerable amount of deterioration to bacterial cells, when examined using electron microscope and cell viability analysis.

Keywords: Antibacterial activity; Electron microscopy; Fluorescence microscopy; Sargassum plagiophyllum; Silver chloride nanoparticles.
