STUDY OF ELECTRO-OPTIC INTERACTIONS FOR SILVER NANOPARTICLES

Abstract

Semiconductor nano-materials are more commonly studied than metallic ones. However, recent applications of metallic nanoparticles in biomedicine have sparked intense interest in this area. The controlled particle size combined with the stealth ligand on their surface allows them to hide from the immune system, enabling them to circulate in the blood for longer periods of time. It is vital to study electro-optic interactions for the creation of successful biomedical sensors using silver nanoparticles. In the present study, we examined variations in the extinction spectra and electric field intensity along with variations in light polarization, semiconductor medium, and particle size of silver nanoparticles using Nanosphere Optics Lab Field Simulator. The peak extinction wavelength shows a significant increase with size, along with the bandwidth. There were significant differences in the results due to changes in embedding medium. Hence, we may conclude that the silver nanoparticles may find applications in a variety of fields, including medical, health care, industrial catalyst and consumer products, due to their unique tunable electro-optical properties.
