Green Synthesis and Spectroscopic Characterization of Nanoparticles

Abstract

Nanoparticles have many applications in different fi elds including food and agriculture. Synthesis and characterization of nanoparticles have therefore attracted interest of scientifi c community. Here we review green methods of synthe- sis of metal and metal oxide nanoparticles. We describe synthesis using enzymes, monosaccharides, polysaccharides and biodegradable polymers. We explain the role of vitamins as reducing and capping agents in green synthesis of nanoparticles. Microwave assisted synthesis and biobased methods have also been illustrated with examples. We then discuss nanoparticle characterization using UV-Visible spectros- copy and Fourier-transform infrared spectroscopy. Applications in diverse fi elds including water purifi cation are then highlighted. Keywords
