Abstract:
1. A method of manufacturing electrochemical sensors, the method comprising steps of: (a) applying a plurality of working electrodes on a substrate; (b) applying a plurality of counter electrodes on the substrate; (c) positioning a spacer layer over the substrate and the working electrodes and the counter electrodes; (d) overlaying the spacer layer with a second substrate; (e) creating a sample chamber region within the spacer layer comprising a plurality of connected sample chambers between the substrate and the second substrate; and (f) separating a plurality of electrochemical sensors, each electrochemical sensor comprising at least one working electrode planar with at least one counter electrode on the substrate, the substrate and second substrate having generally a similar length and width, and at least one sample chamber between the substrate and the second substrate, the sample chamber having a volume of no more than about 1 microliter and continuous with the at least one sample chamber of an adjacent electrochemical sensor.
