1. A method of forming a biosensor, the method comprising the steps of:
- providing a substrate and a cover including first and second surfaces, positioning a reagent on the substrate, carving a flow channel and at least one secondary channel by laser ablation in the first surface, and coupling the first surface of the cover to the second surface so that the flow channel is aligned with at least a portion of the reagent.

Abstract
A method of forming a biosensor is provided. The method includes providing a substrate and a cover including first and second surfaces, positioning a reagent on the substrate, carving a channel by laser ablation in the first surface, and coupling the first surface of the cover to the second surface. The channel includes a first portion having a first height and a second portion having a second height that is less than the first height.
