57. A method for performing an assay, comprising:
-
applying one or more liquids to a sensor such that a target agent bonds to the sensor along with one or more non-target agents, the sensor configured to detect a component in a liquid and including two or more electrodes positioned on a sensor support; and
removing agents from the sensor such that the portion of the non-target agents removed is larger than the portion of target agents that are removed. - View Dependent Claims (58, 59, 60, 61)
