Abstract:
1. A method for detecting an ionic analyte in a sample in which an analyte is bound to a detection reagent to form a bound complex, comprising the steps of: (A) providing a sensor device comprising: (a) a sample ( (b) a first permeable polymeric hydrogel plate ( (c) an anode ( (d) a cathode ( (e) a voltage generator ( (f) a detector ( (B) adding the ionic analyte and detection reagent in the conductive fluid to the compartment; (C) applying an electrical potential via the voltage generator; and (D) detecting via the detector the bound complex formed from the analyte because the bound complex has a charge that causes it to migrate in a direction opposite from that of the unbound analyte when the electric potential is applied.
