Abstract
Microsensors that include an integrated thermal energy source and an integrated temperature sensor are capable of providing localized heating and temperature control of individual sensing regions within the microsensor. Localized temperature control allows analyte detection to be carried out at the same temperatures or substantially the same temperatures at which the sensor is calibrated. By carrying out the sensing near the calibration temperature, more accurate results can be obtained. In addition, the temperature of the sensing region can be controlled so that chemical reactions involving the analyte in the sensing region occur near their peak reaction rate. Carrying out the sensing near the peak reaction rate improves the sensitivity of the sensor which is important as sensor dimensions decrease and the magnitude of the generated signals decreases.
