Abstract:
1. A sensor array for sensing a plurality of detectable functional groups associated with at least one of chemical moieties and biological moieties on a single molecule, said sensor array comprising: a plurality of working electrodes electrically associated with a single reference electrode, each working electrode forming a transducer, each working electrode provided with a coating of a sensing element comprised of an ionized moiety and a sensing functional group sensitive to at least one of said chemical and biological moieties, each coating sensitive to a different detectable functional group; wherein each of the plurality of working electrodes is configured to be deactivated, after having been previously activated, during activation of an other of the plurality of working electrodes and deposition of the coating on the other of the plurality of working electrodes, such that each working electrode is configured to be coated one electrode at a time.
