  • Object separation device using optical method
    Patent number: 7511263
    Abstract: A method for separation of particles with different sizes. The method introduces radiation in a waveguide, coupled to a second guide in a coupling area, the radiation entraining all particles towards the coupling area, and separates the particles as they pass into the coupling area.
    Type: Grant
    Filed: December 3, 2004
    Date of Patent: March 31, 2009
    Assignee: Commissariat a l'Energie Atomique
    Inventors: Stephane Getin, Alexandra Fuchs, Guillaume Colas, Stephanie Gaugiran

  • Particle sorting method
    Patent number: 7402795
    Abstract: A method for sorting particles, including: marking the particles to modify their optical index, placing the particles on a waveguide of a support, and injecting light radiation into the waveguide, the injecting causing displacement of particles on the waveguide and separation of the particles.
