METHOD AND DEVICE FOR MANIPULATING MICROPARTICLES IN FLUID FLOWS

To manipulate microparticles in a fluid that intersects a first channel or several first channels as a stream, one or more microparticles (14) are exposed to electrical field barriers that change their direction from the direction of flow toward the edge of the flow to a lateral hole (17) of the respective first channel. As a result, microparticles can be moved back and forth between streaming fluids. Preferred applications include treatment, separating, sorting or confinement procedures.
