Abstract
Provided are a microfluidic device, a method of analyzing a sample using the microfluidic device, and a method of measuring dilution ratios. The microfluidic device includes: a sample chamber which accommodates a sample to be tested; a dilution chamber which accommodates a diluent, receives the sample from the sample chamber, and provides a sample diluent; a first concentration detecting chamber which receives the sample from the sample chamber; and a second concentration detecting chamber which receives the sample diluent from the dilution chamber.
Claims12
A microfluidic device comprising:
- a sample chamber which accommodates a sample to be tested;
- a dilution chamber which accommodates a diluent and is connected with the sample chamber by a sample distribution channel, wherein the dilution chamber receives the sample from the sample chamber and provides a sample diluent;
- a first concentration detecting chamber which extends from the sample distribution channel and is disposed between the sample chamber and the dilution chamber, and which receives the sample from the sample chamber;
- a plurality of reaction chambers which accommodate a reagent and receive a portion of the sample diluent from the dilution chamber;
- and
- a second concentration detecting chamber which is disposed between the dilution chamber and the plurality of reaction chambers, and receives the sample diluent from the dilution chamber.
A microfluidic device comprising:
- a sample chamber which accommodates a sample to be tested;
- a sample separator which is connected to the sample chamber, receives the sample from the sample chamber and separates a supernatant from the sample;
- a sample distribution channel which is connected to the sample separator;
- a dilution chamber which accommodates a diluent, receives a portion of the supernatant separated by the sample separator via the sample distribution channel, and provides a sample diluent in which the portion of the supernatant and a diluent are mixed at a predetermined ratio;
- a first concentration detecting chamber which receives another portion of the supernatant separated by the sample separator via the sample distribution channel;
- a measuring chamber which is disposed within the sample distribution channel between the sample separator and the dilution chamber;
- a plurality of reaction chambers which accommodate a reagent and receive another portion of the sample diluent from the dilution chamber;
- and
- a second concentration detecting chamber which is disposed between the dilution chamber and the plurality of reaction chambers and receives a portion of the sample diluent from the dilution chamber.
