Synthesis Of Cerium Oxide Nanoparticles Using Marine Algae Sargassum Wightii Greville Extract: Implications For Antioxidant Applications

Abstract

Owing to their peculiar properties nanoparticles of cerium oxide have gained tremendous attention in recent years. As such, bacteria, fungus and algae are used for the development of CeO2 NPs through the use of both intracellular and extracellular microbial or enzyme cells, proteins and other biomolecule compounds. In this paper we use Sargassum wightii Greville, a biological extract, to synthesize cerium oxide (CeO2) nanoparticles. Algal-biogenic metal oxide synthesis nanoparticles is a safe and economical procedure due to the formation of compact, small nanoparticles. A number of advanced devices, such as UV-visible spectrophotometers, XRD, FTIR and SEM spectroscopy have been identified for prepared CeO2 NPs. Cerium oxide particles were studied for the antioxidant properties and their antioxidant potency was examined using an in vitro system. The antioxidant strength tests for insoluble solids were conducted using an modified DPPH process. DPPH spray increases with particle size decrease.
