Abstract
Provided are mass and heat flow measurement sensors comprising a microresonator, such as a quartz crystal microbalance; a heat flow sensor, such as an isothermal heat conduction calorimeter; and a heat sink coupled thermally to the heat flow sensor. The microresonator may be used to measure changes of mass due to a sample at its surface, and heat flow sensor, which is coupled thermally to the microresonator, may be used to measure heat flow from the sample on the surface of the microresonator to the heat sink. Also provided are methods for measuring the mass of a sample and the flow of heat from the sample to the heat sink by utilizing such mass and heat flow measurement sensors.
