The invention relates to an electrode arrangement (10) in a microsystem which is installed in a channel (21) for dielectrophoretically manipulating particles (30) in a suspension liquid. At least one electrode (11, 11a, 11b, 12) is located on a side wall of the channel (21). The electrode (11, 11a, 11b, 12) consists of a number of electrode segments which are configured for generating at least one field gradient for influencing the paths of movement of the particles in the channel (21). According to one embodiment, the particles (30) move in the microsystem due to the effect of the centrifugal and/or gravitational forces. |
