SENSOR CHIP, SENSOR CARTRIDGE, AND DETECTION APPARATUS

摘要

A sensor chip capable of reliably combining propagating surface plasmon resonance with localized surface plasmon resonance of metal nanostructures is provided. A sensor chip includes a metal grating. The metal grating includes multiple long metal pieces extending in a first direction. The long metal pieces are arranged at a pitch smaller than the wavelength of an excitation light. A dielectric layer covers the surface of the metal grating. A linear concavo-convex pattern which extends in a second direction intersecting the first direction is formed on the dielectric layer. Metal nanostructures are placed on the surface of the dielectric layer.
