Abstract
A detection apparatus includes: a substrate; a metal nanostructure on a surface of the substrate and on which immobilized antibodies having a property of binding with a detection object substance are immobilized, the metal microstructure generating a surface plasmon by being irradiated with excitation light; an introducer that introduces labeled antibodies having a property of binding with the detection object substance and labeled with a fluorescent material, and a test solution containing the detection object substance into the metal nanostructure; a light source that irradiates the metal nanostructure with the excitation light from the back surface side of the substrate; and a photodetector that detects the detection object substance based on fluorescence generated from the fluorescent material in response to irradiation of the excitation light. The metal nanostructure includes a light transmissive portion that transmits, to the surface side of the substrate, the excitation light emitted from the back surface side thereof.
