1. A biosensor comprising:
- a substrate, at least a portion being non-embossed, a reagent positioned on the non-embossed portion of the substrate, and a cover positioned on the substrate, the cover including a top side and a generally flat non-embossed bottom side, the bottom side being sealed onto the substrate to define a sealed portion having an interior border and an unsealed portion positioned within the interior border of the sealed portion, at least a portion of the unsealed portion of the generally flat non-embossed bottom side cooperating with the substrate to define a channel positioned between the cover and the substrate, having sides defined by the interior border and extending across the reagent.

Abstract
A biosensor is provided that comprises a substrate, a reagent positioned on the substrate, and a cover including a top side and a generally flat bottom side. The bottom side is coupled to the substrate to define a sealed portion and an unsealed portion. The unsealed portion cooperates with the substrate to define a channel extending across the reagent.

27. A method of forming a biosensor having a capillary channel, the method comprising the steps of:
-
providing a substrate, positioning a reagent on the substrate, providing a cover having a top surface and a non-embossed bottom surface, placing a thermoset adhesive on the bottom surface of the cover, placing the adhesive-coated bottom surface on the substrate, and heating portions of the thermoset adhesive to couple the bottom side to the substrate to define a sealed portion having an interior border and an unsealed portion positioned within the interior border, the unsealed portion cooperating with the substrate to define a capillary channel positioned between the cover and the substrate, having sides defined by the interior border and extending across the reagent. - View Dependent Claims (28, 29)
