Characterization Analysis of Silver Nanoparticles Synthesized from Chaetoceros calcitrans

Abstract

The marine microalgae Chaetoceros calcitrans were used in the synthesis of silver or argentum nanoparticles. The reduction of silver nitrate to silver nanoparticles is observed in marine microalgae. The silver nanoparticles have a good imperative role in technological fields. The synthesis of silver nanoparticles from marine microalgae is a green nanotechnological method. The silver nanoparticle characterization is then carried out. The presence of silver nanoparticles is confirmed by UV-Vis spectroscopy. Fourier transform infrared spectroscopy, atomic force microscopy, photoluminescence, and X-ray diffractometry were used for the characterization analysis of synthesized silver nanoparticles. The research on the antimicrobial activity of silver nanoparticles is made to analyze the antagonistic nature against pathogenic organisms.
