SENSOR-USE ELECTRODE BODY, SENSOR USING SAME, SENSING SYSTEM, AND METHOD FOR MANUFACTURING SENSOR-USE ELECTRODE BODY

摘要

PROBLEM TO BE SOLVED: To provide an excellent sensor-use electrode body and a sensing system, which can detect a target substance sensitively and precisely by forming a substance adsorbing thin-film layer using not mere particles but ultrafine particles and electrically controlling adsorption of a specific substance thereon, and to provide a method for manufacturing the sensor-use electrode body.

SOLUTION: The sensor-use electrode body includes a conductive structure having the substance adsorbing thin-film layer which is made up from a dispersion liquid including Prussian blue type metal-complex ultrafine particles each having a protection ligand. A voltage is applied to the conductive structure in order to electrically control the electrode body, and a selective change in electric characteristic occurring when the target substance is adsorbed to the surface of the substance adsorbing thin-film layer, is measured, thereby detecting the target substance.
