1. A biosensor for use in detecting a target analyte in a fluid sample, the device comprising:

  • a reaction chamber including an immobilized binding site and a probe conjugate, wherein the probe conjugate comprises a binding partner adapted to bind to the immobilized binding site;

    a detection chamber including electrodes for detecting an electrochemical reaction in the detection chamber; and

    a fluid passageway between the reaction chamber and the detection chamber, wherein, the presence or absence of a target analyte in the fluid sample results in a change in the amount of probe conjugate bound in the reaction chamber, the change detectable with an electrochemical reaction in the detection chamber.
