ABSTRACT:
The metal fine particles33are sparsely fixed on the surface of the transparent substrate32, and the acceptor35for attaching the specific ligand is immobilized on the transparent substrate32or the metal fine particles33. The prism36is closely attached to the lower surface of the transparent substrate32, and the excitation light enters the transparent substrate32through the prism36. The incident light is totally reflected at the surface of the transparent substrate32, and the evanescent light generated at the surface and the metal fine particles33locally 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 particles33and the acceptor35is 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.
