Abstrakt: Combining dielectrophoretic and hydrodynamic forces in micro electrode structures allows enrichment and stable trapping of viruses in aqueous solutions. Fluorescently labelled Influenzaand Sendaiviruses were collected from solutions of 2*105– 2*108viruses/μl within a few seconds. In the central part of the trap a virus aggregate of about 2–9 μm in diameter was formed. This corresponds to a local enrichment of viruses up to a factor of about 1400.
