| 摘要 |
This invention relates to a microfluidic device for the manipulation of a non-magnetic liquid, comprising at least one cell comprising: an enclosure ensuring the confinement of a magnetic liquid (5), immiscible with the non-magnetic liquid (7) to be manipulated, magnetic means (6) associated with the enclosure and permitting local application to the magnetic liquid of a magnetic field whose energy profile has a depression, giving rise to at least one volume for reception of the non-magnetic liquid, by forcing the magnetic liquid back, the magnetic field being displaceable to permit a manipulation of the non-magnetic liquid between means for introduction (3) and means for evacuation (4).
