BIOSENSOR AND MEASURING METHOD EMPLOYING SAME
First Claim
1. A biosensor for measuring concentrations of first and second substrates in a sample, comprising:
- a sensor unit including a base plate, an electrode provided over said base plate, and a reaction layer provided over said electrode;
a timing unit for measuring time; and
a calculating unit,wherein said reaction layer comprises a first enzyme for converting said first substrate into said second substrate, and a second enzyme acting on said second substrate or a converted substance obtainable by further converting said second substrate, andwherein said calculating unit calculates a concentration of said first substrate and a concentration of said second substrate in said sample respectively, on the basis of a first current value detected in said sensor unit at a first time and a second current value detected in said sensor unit at a second time.

Abstract
A biosensor is a bio sensor for measuring concentrations of first and second substrates in a sample, including a sensor unit including an insulating base plate, an electrode over the insulating base plate, and a reaction layer over the electrode; a timing unit for measuring time; and a calculating unit, in which the reaction layer contains a first enzyme for converting the first substrate into the second substrate, and a second enzyme acting on the second substrate or the converted substance obtainable by further converting the second substrate, and the calculating unit calculates concentrations of the first and the second substrates in the sample, on the basis of a first current value detected in the sensor unit at a first time and a second current value detected in the sensor unit at a second time.
