REAGENT LAYER INCLUDING CONDUCTIVE CARBON FILLER, SENSOR HAVING REAGENT LAYER, AND METHOD FOR FORMING REAGENT LAYER

原文（中文）

An object of the present invention is to provide a reagent layer for preparing an electrochemical sensor that can detect an analyte with high sensitivity and/or that is suitable for measurement over a long period (continuous monitoring) and excellent in durability, and a method for forming the same. The reagent layer according to the present invention comprises a conductive carbon filler (a), an anionic dispersant (b), and a cationic mediator (c). The method for forming a reagent layer according to the present invention comprises the steps of: (1) preparing a reagent solution containing a conductive carbon filler (a), an anionic dispersant (b), and a cationic mediator (c); (2) applying the reagent solution to a reagent layer formation site; and (3) drying the applied reagent solution to form a reagent layer.
