A microfluidic system for analyzing nucleic acid, the microfluidic system including a reagent supply device including a sample chamber into which a sample can be injected, one or more reagent chambers for containing one or more reagents for extracting nucleic acid from the sample, and a waste chamber in which the used reagent can be discarded; a binding-lysis chamber in which cells are captured from the sample and lysed to form a cell lysate containing nucleic acid; plurality of particles for cell binding disposed in the binding-lysis chamber; a plurality of rehydration chambers into which the cell lysate formed in the binding-lysis chamber can be distributed and mixed with a nucleic acid amplification reagent to form an amplification reaction mixture; a plurality of amplification chambers in which a nucleic acid amplification reaction is performed on the amplification reaction mixture introduced from the plurality of rehydration chambers; and a flow channel system including an outlet and a plurality of inlets connected to the reagent supply device and forming an integrated fluid flow between the binding-lysis chamber, the rehydration chambers, and the amplification chambers. |
