Abstract

DNA hybridization can be measured with enhanced sensitivity based on localized surface plasmon (LSP) induced by surface nanowire structure. Changes made to the structure result in higher plasmon momentum, which can be coupled to a particle plasmon induced by gold nanoparticles to which DNA molecules are adsorbed. With the insight gained from near-field pattern via calculation, target localization effect is also experimentally shown. We expect that orders of magnitude can be improved in terms of sensitivity if one is to combine the effect of particle-to-LSP coupling and target localization scheme.
