1. A sensor array which is monolithically integrated at least one of in and on a substrate, comprising:

  • at least three electrodes, designed as biosensor arrangements for detection of biomolecules; and

    a switching unit, designed such that at least one of the at least three electrodes is selectively connected as a working electrode, which is coupled to an electrolytic analyte, the other electrodes of the at least three electrodes being connected as an opposing electrode, wherein the at least three electrodes are designed such that sensor events take place at the one electrode, connected as a working electrode, of the at least three electrodes in the electrolyte solution when in the presence of the electrolytic analyte.
