電極基板、作用電極および検査チップ

Electrode substrate, working electrode and inspection chip

Abstract

PROBLEM TO BE SOLVED: To provide an electrode substrate, a working electrode and an inspection chip which can detect with high sensitivity a substance to be detected or inspected.SOLUTION: A nonconductive layer 63 is prepared in addition to a region for disposing the substance to be detected on a working electrode body 62 comprising a semiconductor formed on a substrate body 40a of an electrode substrate 40 used to photoelectrochemically detect the substance to be detected which emits electrons by photoexcitation.
【課題】検出物質や被検物質を高い感度で検出することができる、電極基板、作用電極および検査チップを提供する。 【解決手段】光励起により電子を生じる検出物質を光電気化学的に検出するのに用いられる電極基板40の基板本体40a上に形成された半導体からなる作用電極本体62における検出物質を存在させる領域以外に、非導電層63を設ける。 【選択図】図6
