We propose and theoretically analyze a novel sensor based on plasmonic mode interference in a one-dimensional degenerate n-doped silicon core waveguide. The waveguide supports both, the symmetric- as well as anti-symmetric surface plasmon polaritons

Gold nanobipyramids (GNBPs) have high selectivity in detecting changes in their surrounding medium because of their electric field enhancements and larger surface areas. In this study, we functionalized GNBPs using a thiol group that acts as a ligand

It is very important to determine the presence of toxic Cr(VI) in aqueous environment. Detection of Cr(VI) using AuNPs has been carried out based on the oxidation or etching principle, which results in the change of localized surface plasmon resonanc
