Abstract:
1. A microfluidic device, comprising: a microchannel which is closed from an outside atmosphere, and is configured to transport a sample liquid; an inlet reservoir which is configured to reserve the sample liquid to be introduced into the microchannel; an inlet which is positioned on a sample-introduced side of the microchannel and communicates with the inlet reservoir; an outlet which is positioned on a sample-discharged side opposite of the sample-introduced side of the microchannel; an open channel which is different from the microchannel, is communicating with the outlet of the microchannel, and has a side surface opened to the outside atmosphere; an outlet reservoir which is communicating with the open channel and is configured to reserve the sample liquid discharged from the open channel; and a sample recovery port which is configured to recover the sample liquid from the outlet reservoir, wherein the inlet is positioned at a higher position in a gravity direction than the outlet, the open channel has the side surface extended in the gravity direction such that the sample liquid is flown out of the outlet and is guided along with the side surface and removed from the outlet of the microchannel, and the open channel has a terminal which reaches the lowest point of the outlet reservoir such that the sample liquid is configured to flow from the outlet toward the terminal of the open channel such that the sample liquid is reserved in the outlet reservoir.
