Abstract

A method and a device for position and/or type-selective control of the position and/or change of position of suspended particles in a multielectrode system by the effect of polarization forces that are induced in the particles by alternating electric fields in the multielectrode system, which particles comprise biological or synthetic objects with dimensions essentially corresponding to those of biological cells or cell organelles, viruses or macromolecules, base on the fact that the multielectrode system forms with the particle suspension an electrical network, in which means of resonance are provided for creating a resonant increase or damping of the field strength of the alternating electric fields at certain frequencies in at least one locally demarcated region of the multielectrode system.
