METHOD, TOOL AND DEVICE FOR MEASURING CONCENTRATION

WIPO Patent Application WO/2003/025558

A1

A method for measuring a concentration of a substance to be measured, wherein a reaction system comprising the substance to be measured, an oxidation−reduction enzyme and an electron mediator is provided, and an electrochemical technique is used, characterized in that use is made of a Ru compound as the electron mediator&semi and a tool for measuring a concentration having a substrate, at least a first and a second electrodes formed on the substrate, and a reagent layer in a solid form, characterized in that the solid reagent layer comprises an oxidation−reduction enzyme and a Ru compound, and dissolves and forms a liquid reaction system when a sample solution is supplied.
