Abstract:
1. A system for distributing a reagent in a channel formed on a chip of a microfluidic device to perform a test on the reagent, the system comprising: the microfluidic device including: wherein 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 only one kind of a liquid driven by the micropump and that has physical properties different from physical properties of the reagent, 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 in an indirect manner.
