Abstract:
1. A biosensor for determining a concentration of glucose in a sample, the biosensor comprising: a first substrate and a second substrate disposed over the first substrate, wherein the first and second substrates define a sensor comprising a proximal end and a distal end, the distal end being configured for insertion into a sensor reader, wherein the proximal end comprises a narrow portion as compared to the distal end, and wherein the first substrate comprises a length extending from the proximal end to the distal end and the second substrate comprises a length extending from the proximal end to the distal end, wherein the length of the second substrate is greater than the length of the first substrate; a spacer layer disposed between the first and second substrates and defining an aperture along a first side edge of the sensor configured to receive a sample fluid; a working electrode disposed on the narrow portion of the proximal end of the first substrate and extending to the distal end of the first substrate; a mediator and a glucose dehydrogenase disposed on the working electrode; and a counter/reference electrode disposed on the narrow portion of the proximal end of the second substrate and extending to the distal end of the second substrate.
