ABSTRACT:
A sensor is provided for detecting a target substance in a sample by detecting a product formed in the presence of an enzyme and an enzyme substrate. The sensor comprises two or more working electrodes, a first capturing molecule immobilized on the working electrodes, and a current-detector for detecting a current value flowing through at least one of the working electrodes. The sensor also comprises a target substance detection means having an arithmetic unit for determining an amount of the target substance in the sample on the basis of the current value detected by the current-detector in a specified period of time, and a crosstalk detecting electrode arranged between the working electrodes for detecting a crosstalk between the working electrodes. The specified period of time is a time necessary for the current value through the crosstalk detecting electrode to show a particular change.
