Abstract

See full text

A method is provided for measuring a substance using a biosensor, the method comprising:

    introducing a sample containing the substance into an electrochemical measurement cell which comprises an insulating base plate; at least two electrodes formed on the insulating base plate; and a reagent layer that is disposed on at least one of the electrodes and comprises an oxidoreductase;applying a voltage to the electrodes;detecting a charge transfer limiting current which is generated due to the transfer of electrons from the substance in the sample to the electrode; anddetermining the concentration of the substance contained in the sample based on the charge transfer limiting current.
