Abstract:
1. An analyte evaluation apparatus which comprises: an analyte space for holding a liquid containing an analyte; a working electrode; a counter electrode; and a reference electrode, and in which the potential of said working electrode is altered with respect to the potential of said reference electrode as a standard potential and the behavior of said analyte is observed to thereby detect said analyte, wherein: one or more of said working electrodes are provided in said analyte space; one or more of said counter electrodes and one or more of said reference electrodes are provided; at least one of said counter electrodes and said reference electrodes is provided in an electrode medium container which holds an electrically conductive electrode medium and which is provided independently from said analyte space; at least one of said working electrode and a lead thereof has an auxiliary electrode that is exposed inside said electrode medium container; and wherein said analyte comprises a fluorescent label capable of emitting fluorescence in response to received light when the distance between said fluorescent label and said working electrode increases, and said behavior of said analyte is emission and/or quenching behavior of said fluorescence.
