  • Method for treating drops in a microfluid circuit
    Patent number: 8206994
    Abstract: The invention relates to a method for treating drops in a microfluid circuit, comprising at least one microchannel (12) through which the drops flow, characterized in that a laser (26) is brought to bear on the interface of said drops in the transport liquid (F3), or on the interface of drops in contact, in order to carry out a sorting of the drops, to form nanodrops from a larger drop or to fuse drops (60, 64) in contact and initiate reactions between the fluids contained in said drops.
    Type: Grant
    Filed: May 16, 2007
    Date of Patent: June 26, 2012
    Assignees: Centre National de la Recherche Scientifique, Ecole Polytechnique
    Inventors: Charles N Baroud, Jean-Pierre Delville
  • Microfluidic circuit having an active component
    Patent number: 8136553
    Abstract: A microfluidic circuit comprising microchannels (24, 26) containing different fluids (F1, F2), with a laser beam being focused at (32) on an interface (30) between the fluids so as to form a pump, a valve, or a mixer, for example.
