Abstract
A method for determining the quality of a microfluidic device, the method including placing a microfluidic device including a valve on a stage; radiating light on the valve of the microfluidic device; detecting light reflected from the valve using a photodetector; opening the valve of the microfluidic device; and comparing a change of the light reflected from the valve when the valve is opened with previously-stored reference data to evaluate a quality of the microfluidic device, wherein the valve of the microfluidic device includes a valve seat, which protrudes into a microfluidic path, and a polymer film, which opens and closes the valve.
Claims25
A method of determining the quality of a microfluidic device, the
- method comprising:
- placing a microfluidic device comprising a value on a stage;
- radiating light on the value of the microfluidic device;
- detecting light reflected from the valve using a photodetector;
- opening the valve of the microfluidic device;
- and
- comparing a change of the light reflected from the valve by a controller when the valve is opened with previously-stored reference data to evaluate a quality of the microfluidic device,
- wherein the valve of the microfluidic device comprises a valve seat, which protrudes into a microfluidic path, and a polymer film, which opens and closes the valve.
An apparatus for determining the quality of a microfluidic device, the apparatus comprising:
- a stage on which a microfluidic device comprising a valve is placed;
- a light source positioned to radiate light on the valve of the microfluidic device;
- a photodetector positioned to detect light reflected from the valve;
- and
- a controller, which compares a change of the light reflected from the valve when the valve is opened with previously-stored reference data to determine a quality of the microfluidic device.
