34. A sensor for determining the concentration of a ketone body in a sample, the sensor comprising:
-
a first substrate, a second substrate, and a spacer layer therebetween; a sample chamber defined between the first substrate and the second substrate bounded by the spacer layer, the sample chamber having at least one inlet; a protrusion extending from the first substrate at the inlet. - View Dependent Claims (35, 36, 37)
