20. A method of forming biosensor, the method comprising the steps of:
-
providing a substrate, a reagent for the measurement of at least one analyte, and a cover, the cover including a first surface, exposing the cover to at least one pulse of light of sufficient to ablate the first surface in a pre-determined pattern creating a channel, cleaning the first surface of the cover so that the surface energy of the channel ranges from about 60 mN/m to about 72 mN/m, and placing the first surface of the cover upon the substrate to define a capillary path and the reagent is positioned in the capillary path. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
