Abstract

Electrode arrangement (10) in a microsystem adapted for dielectrophoretic manipulation of particles (30) in a suspension fluid in a channel (21), wherein at least one electrode (11, 11a, 11b, 12) is arranged on a lateral wall of the channel (21), the electrode (11, 11a, 11b, 12) consisting of a plurality of electrode segments adapted to generate at least one field gradient for influencing the movement paths of the particles (30) in the channel (21). In one embodiment of the invention, the particles are moved in the microsystem by exposure to centrifugal and/or gravitational forces.
