Abstract
A method for thermal control of microfluid and a device using the thermal control method utilizes a chip provided with a microchannel and a pneumatic microflow driving element to drive a microfluid back and forth in the microchannel at a predetermined frequency. Heating devices are arranged along specific sections of the microchannel. By controlling the frequency of the back-and-forth movement of the microfluid, the temperature of the microfluid may be accurately controlled. Due to the rapid movement of the microfluid in the microchannel, uniform distribution of the temperature and ingredients in the microfluid may also be obtained.
