Abstract
A biosensor strip having a low profile for reducing the volume of liquid sample needed to perform an assay. In one embodiment, the biosensor strip includes an electrode support; an electrode arrangement on the electrode support; a cover; a sample chamber; and an incompressible element placed between the cover and the electrode support, the incompressible element providing an opening in at least one side or in the distal end of the sample chamber to provide at least one vent in the sample chamber. In another embodiment, the biosensor strip has an electrode support; an electrode arrangement on the electrode support; a cover; and a sample chamber, the cover having a plurality of openings formed therein, at least one of the openings in register with the sample chamber. The invention further includes methods for preparing such a biosensor strips in a continuous manner.

44. A method of determining the concentration of an analyte in a sample, the method comprising:
-
contacting the sample with a biosensor, wherein the biosensor comprises a spacer layer that provides a sample chamber between an electrode support and a cover, wherein at least a portion of an electrode arrangement is located within the sample chamber, and wherein an incompressible element placed in-between said cover and said spacer layer provides at least one vent in the sample chamber; wherein said biosensor is configured to determine the concentration of an analyte in said sample. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)

65. A method of determining the concentration of an analyte in a sample, the method comprising:
-
contacting the sample with a biosensor, wherein the biosensor comprises a spacer layer that provides a sample flow channel having a proximal end, a distal end, a first side, and a second side, wherein the sample is introduced to said flow channel at said proximal end and flows towards said distal end, and wherein said first and second sides serve to retain the sample within said flow channel, and wherein said biosensor comprises an electrode support, a cover, and an incompressible element placed in-between said cover and said spacer layer, wherein said incompressible element is positioned at or near said distal end of said sample flow channel and provides at least one vent in said sample flow channel; wherein said biosensor is configured to determine the concentration of an analyte in said sample. - View Dependent Claims (66, 67, 68, 69, 70, 71)
