Analyte sensors and methods of use

摘要

Analyte sensors for determining the concentration of an analyte in a sample. The sensors have a sample chamber having an inlet with a projection extending from an edge of the sensor for facilitating flow of sample into the sample chamber.

1. A method of determining concentration of an analyte, comprising:
depositing a sample of biological fluid on a biosensor positioned in an analyte meter, the biosensor comprising:
a first substrate, a second substrate, and a spacer layer therebetween forming the biosensor, wherein the biosensor comprises a proximal end and a distal end;a sample chamber defined between the first substrate and the second substrate bounded by the spacer layer at the proximal end of the biosensor, the sample chamber having a first inlet and a second inlet; anda first protrusion extending from the first substrate at the first inlet and a second protrusion extending from the first substrate at the second inlet; electrolyzing the sample; and determining the concentration of analyte in the biological fluid sample.
