57AbstractABEin Verfahren bzw. eine Steuervorrichtung zur orts- und/oder typselektiven Steuerung der Position und/oder der Positionsänderung suspendierter Partikel in einem Multielektrodensystem unter der Wirkung von Polarisationskräften, die in den Partikeln durch elektrische Wechselfelder in dem Multielektrodensystem induziert werden, welche Partikel biologische oder synthetische Objekte mit Abmessungen umfassen, die im wesentlichen denen von biologischen Zellen oder Zellorganellen, Viren oder Makromolekülen entsprechen, basiert darauf, daß das Multielektrodensystem mit der Partikelsuspension ein elektrisches Netzwerk bildet, in dem Resonanzmittel zur Ausbildung einer resonanten Erhöhung oder Dämpfung der Feldstärke der elektrischen Wechselfelder bei bestimmten Frequenzen in mindestens einem lokal abgegrenzten Bereich in dem Multielektrodensystem vorgesehen sind.
