Analyte sensors and methods of use
First Claim
1. An analyte sensor for determining the concentration of an analyte in a sample, the sensor comprising a sample chamber having an inlet with a width and a protrusion extending from an edge of the sensor proximate the inlet, the protrusion having a width that is less than the inlet width,wherein the sensor comprises a first substrate and a second substrate, a spacer between the first substrate and the second substrate, together the first substrate, second substrate and spacer defining the inlet, and wherein the protrusion is defined by the first substrate and the sensor further comprises a second protrusion defined by the second substrate.
