Abstract

The metal fine particlesare sparsely fixed on the surface of the transparent substrate, and the acceptorfor attaching the specific ligand is immobilized on the transparent substrateor the metal fine particles. The prismis closely attached to the lower surface of the transparent substrate, and the excitation light enters the transparent substratethrough the prism. The incident light is totally reflected at the surface of the transparent substrate, and the evanescent light generated at the surface and the metal fine particleslocally plasmon resonate. As the evanescent light and the metal fine particles locally plasmon resonate, a strong electric field is enclosed in the vicinity of the metal fine particles. When the surface arranged with the metal fine particlesand the acceptoris contacted to the analysis sample solution containing ligand modified with light emitting molecules, only the light emitting molecule modifying a specific ligand attached to the acceptor emits light.
