摘要:
Provided is a centrifugal force based microfluidic system including: a microfluidic device including a rotatable platform and an optical path formed to extend horizontally in a straight line from a circumference of the platform; a motor rotating so as to control the microfluidic device; a light emitting unit emitting light towards the microfluidic device; a light receiving unit detecting the light emitted from the light emitting unit; and a controller determining a home position to be the position of the microfluidic device at a point of time when the light emitted from the light emitting unit is detected by the light receiving unit, wherein the light emitted from the light emitting unit passes through the optical path to be incident on the light receiving unit only when the microfluidic device is located in a predetermined position.
