PROBLEM TO BE SOLVED: To provide a device not producing H2O2 having cytotoxicity, unnecessary for holding the enzymatic power of glucose oxidase and dispensing with the formation of an electrochemical circuit by the flow of a current.SOLUTION: A detection area 248 being an optical resonator and a reservoir area 240 are formed in a chamber 220 and a detection area 250 being the optical resonator is formed in a chamber 222. A fluid is allowed to go in and out of the chambers 220 and 222 through filters 224 and 228. Concanavalin A (ConA) molecules 236 or sephadex beads 238 in the area 240 go in and out of the area 248 in the chamber 220 through a mesh 242. The movement of them is affected by the concentration of the specimen in the fluid. The light from a light source part 204 is guided to the areas 248 and 250 and, when emitted lights 230 and 232 are detected by a detection part 234, a detection result 234 showing the concentration of the specimen is obtained.COPYRIGHT: (C)2010,JPO&INPIT【課題】細胞毒性のあるH2O2を産生せず、グルコースオキシダーゼの酵素力を保つ必要がなく、電流を流して電気化学回路を形成する必要がないデバイスを提供する。【解決手段】室220内に光共振器たる検知エリア248及びリザーバエリア240を形成し、室222内に光共振器たる検知エリア250を形成する。室220,222内にフィルタ224,228を介し流体を出入りさせる。エリア240内のコンカナバリンA(ConA)分子236やセファデックスビーズ238はメッシュ242を介し室220内エリア248に出入りする。その動きは流体内検体濃度に左右される。光源部204からの光をエリア248,250に案内し、出射光230,232を検知部234にて検知すると、その検体濃度を示す検知結果234が得られる。【選択図】図2
