Abstract
Disclosed herein are methods and mid-IR detection apparatus to measure analytes in gas or liquid phase. Solid state cooling of a crystalline lattice is effectively achieved with the controlled flow of charge carriers that absorb thermal energy from the semiconductor material which senses mid-IR photons. Reduction in temperature improves signal-to-noise ratios thus improving molecular sensitivity. In one embodiment the apparatus is used to detect a biomarker.
