Abstract:
1. An electrochemical device, comprising: a first electrically conductive layer including a first electrode area and an opposing second electrically conductive layer including a second electrode area, wherein at least one of the first or second electrically conductive layers comprises an electrically conductive material and an insulating material, wherein the electrically conductive material is coextensive with the insulating material; a spacing layer positioned between the first and second electrically conductive layers and a sealing layer positioned adjacent to one of the first and second electrically conductive layers; an electrochemical cell defined by the first and second electrically conductive layers, and an opening in the spacing layer; an immunological cell defined by one of the first and second electrically conductive layers, the sealing layer, and an opening in the spacing layer and at least one of the first and second electrically conductive layers; first and second electrical contact areas spaced laterally from the electrochemical cell; and a sample passageway between the electrochemical cell and the immunological cell, wherein a sample can flow from the immunological cell to at least a portion of the electrochemical cell through the sample passageway.
