Index matching sheet-integrated spr measurement chip

PROBLEM TO BE SOLVED: To provide a chip for SPR measurement allowing the use of a low-priced transparent substrate with a metallic thin film formed thereon without using matching oil and facilitating the replacement of the substrate, with regard to an SPR optical system. SOLUTION: This chip 200 for SPR measurement used in an SPR optical system 310 includes a transparent substrate 202 comprising a metallic thin film 203 for SPR measurement, and further, a transparent elastic adhesive sheet 201 on a surface of the transparent substrate 202 on the opposite side of the thin film 203. The adhesive sheet 201 is formed directly on the transparent substrate 202, and has the same refractive index as a prism 303 and the transparent substrate 202 have. COPYRIGHT: (C)2010,JPO&INPIT
