Abstract
A microfluidic device includes: a lower plate having a first channel; a first upper plate fixedly stacked on the lower plate and having grooves on an upper portion thereof, a fluid inlet and a fluid outlet formed at positions corresponding to both ends of the first channel; and a second upper plate movably inserted into the grooves of the first upper plate and including a second channel, a hole connected to a right end of the second channel, and a third channel connected to the right side of the hole.
Claims15
A microfluidic device comprising:
- a lower plate having a first channel;
- a first upper plate fixedly stacked on the lower plate and having grooves on an upper portion thereof, a fluid inlet and a fluid outlet formed at positions corresponding to both ends of the first channel;
- and
- a second upper plate movably inserted into the grooves of the first upper plate and including a second channel, a hole connected to a right end of the second channel, and a third channel connected to the right side of the hole.
A method for controlling a fluid flow by using a microfluidic device formed by sequentially stacking a lower plate, a first upper plate, and a second upper plate such that the first upper plate is fixed to an upper portion of the lower plate, and the second upper plate is movably inserted into grooves of the first upper plate, the method comprising:
- injecting a fluid to a first channel formed on the lower plate through a fluid inlet formed on the first upper plate;
- and
- when the first channel is filled with the fluid injected through the fluid inlet so the fluid flow is stopped, moving the second upper plate to connect a fluid outlet formed on the first upper plate and a second channel formed on the second upper plate.
