Apparatus and method for gene amplification

An apparatus for detecting a microfluid, the apparatus comprising:

• a gene amplifier;
• an optical unit comprising a light emitter and a light detector to emit light onto a sample solution and to measure an optical signal scattered or reflected from the sample solution, while a gene amplification reaction is performed in a gene amplification chip of the gene amplifier, or after the gene amplification reaction is complete;
• and
• a processor configured to detect an amplified gene by analyzing the optical signal,
• wherein the gene amplifier comprises:
• an upper main body comprising a first inlet to receive a sealing solution, a second inlet to receive the sample solution, and an upper passage that allows the sample solution and the sealing solution to move by capillary action;
• a lower main body disposed to oppose the upper main body, and having a lower passage through which the sealing solution moves by capillary action after being injected from the first inlet of the upper main body;
• the gene amplification chip configured to be inserted between the upper main body and the lower main body;
• and
• a porous medium configured to be inserted between the upper main body and the lower main body.
