Biosensors and methods of preparing same
First Claim
1. A method of manufacturing a plurality of individual biosensors, the method comprising:
- combining;
a substrate comprising a plurality of electrode arrangements,a spacer layer,a length of an incompressible element, anda coverto provide a plurality of biosensors; and
separating the plurality of biosensors to provide a plurality of individual biosensors comprising a sample chamber, the sample chamber comprising a proximal end where a sample is introduced into the sample chamber and a distal end toward which the sample flows, wherein the incompressible element is placed in-between the cover and the spacer layer to provide at least one vent in the sample chamber, wherein the incompressible element is positioned only at the distal end of the sample chamber or only near the distal end of the sample chamber.

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.
