  • Publication number: 20200330989
    Abstract: There is provided a microfluidic device for capturing particles comprising a particle capturing chamber (100) including at least: a particle capturing unit (101) including one of at least one well (106) or at least one through hole (108); and a particle capturing channel unit (102) used for capturing a particle in the well or with the through hole, in which the particle is captured in the well or with the through hole by being sucked, via the particle capturing channel unit, in a direction opposite to a direction (114) on which the particle settles. Such a configuration has for result that the particles that are not captured in the well or with the through hole are prevented from staying in the vicinity of the well or the through hole of the particle capturing unit when suction is stopped.
