Abstract

The invention relates to a method for the separation of a polarizable bioparticle comprising the steps: a) dielectrophoretic preseparation of a polarizable bioparticle from a suspension of bioparticles; b) fluidic separation of the selected bioparticle by fixing the bioparticle in a dielectrophoretic field cage and circulating fluid around the bioparticle; c) transferring the separated bioparticle from the dielectrophoretic field cage to a culture chamber; d) dielectrophoretic fixing of the separated bioparticle in the culture chamber and study, observation, manipulation and/or culturing of the separated bioparticle. The invention further relates to a microfluidic system and use thereof.
