Abstract:
1. A method for manufacturing a biosensor for detecting one or more analytes in a fluid sample, comprising: a generally planar base layer having a proximal end and a distal end; depositing a conductive layer on the base layer, the conductive layer comprising a plurality of electrodes disposed on the base layer near the proximal end, and a plurality of electrical contacts disposed on the base layer near the distal end; forming a first capillary chamber on the base layer having a first opening at the proximal end, wherein the first capillary chamber includes at least a working electrode and a counter electrode selected from the plurality of electrodes, wherein the working electrode and the counter electrode are configured to operate in conjunction to detect the one or more analytes in the fluid sample; forming a second capillary chamber having a second opening at the proximal end separate from the first opening, wherein the second capillary chamber is configured to include at least one electrode selected from the plurality of electrodes excluding the working electrode; and forming a reagent layer on the base layer, the reagent layer formed to at least partially cover the first capillary chamber.
