Abstract
Provided is a glucose sensor that is capable of measuring a glucose concentration even in the case where Aspergillus oryzae type FAD-GDH (flavin adenine dinucleotide-glucose dehyrogenase) and a ruthenium compound are used in combination. The glucose sensor includes an insulative substrate, an electrode system having a working electrode and a counter electrode provided on the substrate, and a reagent layer provided on the electrode system, wherein the reagent layer contains Aspergillus oryzae type FAD-GDH, a ruthenium compound, and PMS (phenazine methosulfate).
Claims11
A glucose sensor comprising:
- an insulative substrate;
- an electrode system having a working electrode and a counter electrode provided on the substrate;
- and
- a reagent layer provided on the electrode system,
- wherein the reagent layer contains Aspergillus oryzae type flavin adenine dinucleotide-dependent glucose dehydrogenase (FAD-GDH), a ruthenium compound, and phenazine methosulfate (PMS).
A method for measuring a concentration of glucose in a sample, the method comprising:
- bringing the sample and Aspergillus oryzae type FAD-GDH into contact with each other;
- and
- electrochemically measuring a reaction between the glucose in the sample and the Aspergillus oryzae type FAD-GDH via PMS and a ruthenium compound.
A method for producing a glucose sensor, the method comprising forming a reagent layer containing Aspergillus oryzae type FAD-GDH, a ruthenium compound, and PMS on an electrode system provided on an insulative substrate;
- the electrode system having a working electrode and a counter electrode provided on the insulative substrate.
