  • Dielectrophoretic process for retaining polarizable target-particles and device for performing that process
    Patent number: 8329015
    Abstract: A process and a device for retaining polarizable target-particles from a fluid suspension of polarizable target-particles comprising the steps of pumping that suspension into a vertical or inclined channel and applying an alternating electric field inducing a negative dielectrophoretic force on the target-particles, the force being sufficient to push them a distance of at least or about 25 m from the surface of an electrode-bearing wall, thereby creating an upward-moving clarified fluid zone in the vicinity of that wall and a downward-moving target-particle containing fluid zone at a distance from that wall.
    Type: Grant
    Filed: June 14, 2005
    Date of Patent: December 11, 2012
    Assignee: Ares Trading S.A.
