Centrifugal force based platform, microfluidic system including the same, and method of determining home position of the platform

摘要

Provided are a centrifugal force based platform (102) formed to be rotatable and including a home mark (105,105A-D) having a retro-reflective property of light, and a centrifugal force based microfluidic system (100) including the platform (102). The method of determining a home position of the centrifugal force based platform (102) includes: rotating the platform (102) formed and including a home mark (105,105A-D) having a retro-reflective property of light; emitting light from a light-emitting unit (130) to the platform (102); and detecting the emitted light, which is retro-reflected by the home mark (105,105A-D), in a light-receiving unit (133), and then determining the home position of the platform (102) based on the detected light.
