Abstract
A microfluidic device for performing a test on the reagent includes a fill port formed on the chip to inject the reagent into at least one of the channels, one or more heating portions for performing a test on the reagent injected into the channel, and a micropump. An inside of the micropump and a vicinity of the channel connecting to an inlet and an outlet of the micropump are filled with a drive solution that is driven by the micropump, a gas is sealed between the reagent and the drive solution in the channel to prevent the reagent from contacting the drive solution directly, and the micropump directly drives the drive solution in the forward and backward directions, so that the reagent is repeatedly moved to the test portions through the gas in an indirect manner or is repeatedly passed through the test portions through the gas.
