A microelectromechanical systems-based calorimetric device includes first and second micromixers and first and second thermally-isolated microchambers. A first solution including a sample and a reagent is introduced to the first microchamber via the first micromixer, and a second solution including a sample and a buffer is introduced to the second microchamber via the second micromixer. A thermopile measures the differential temperature between the first microchamber and the second microchamber and outputs a voltage representative of the difference. The output voltage can be used to calculate reaction parameters.

MEMS-based isothermal titration calorimetry

MEMS-based calorimeter including two microchambers supported in a thin film substrate formed on a polymeric layer is provided. The thin film substrate includes a thermoelectric sensor configured to measure temperature differential between the two microchambers, and also includes a thermally stable and high strength polymeric diaphragm. Methods for fabricating the MEMS-based calorimeter, as well as methods of using the calorimeter to measure thermal properties of materials, such as biomolecules, or thermodynamic properties of chemical reactions or physical interactions, are also provided.
