SPR SENSOR CELL, AND SPR SENSOR

摘要

The present invention provides an SPR sensor cell having very excellent detection sensitivity and an SPR sensor. The SPR sensor cell of the present invention includes a detection unit and a sample mounting portion adjacent to the detection unit, wherein the detection unit includes an under-cladding layer, a core layer formed so that at least a part of the core layer is adjacent to the under-cladding layer, a metal layer covering the core layer, and a protective layer formed between the core layer and the metal layer; and the protective layer is formed of a material having a band gap (Eg) of more than 1.0 eV and less than 7.0 eV.
