✦ Synopsis

Combining dielectrophoretic and hydrodynamic forces in micro electrode structures allows enrichment and stable trapping of viruses in aqueous solutions. Fluorescently labelled Influenza and Sendai viruses were collected from solutions of 2* 1 O5 -2* 10' viruses/y1 within a few seconds. In the central part of the trap a virus aggregate of about 2-9 urn in diameter was formed. This corresponds to a local enrichment of viruses up to a factor of about 1400.
