Abstract
A microfluidic device includes a chamber configured to accommodate a sample and air, and a detection device provided with a light emitter configured to emit light towards the chamber on a light transmission path and a light receiver configured to receive the light, and further configured to measure an optical density of the chamber to determine whether the sample is accommodated in the chamber based on the received light. A boundary between the sample and the air accommodated in the chamber is provided on the light transmission path.
