For object detection, particularly in fluidic microsystems, optical imaging of at least one resting or moving object ( ) on a structured mask ( ) with at least one segment from a flat section ( ), in which the object ( ) is located at least partially or temporarily and which has a characteristic dimension smaller than the dimension of the object ( ) or its movement path, to a detector unit, detection of the quantity of light transmitted by the structured mask ( ), and generation of a detector signal which has a predetermined relationship with the quantity of light, and evaluation of the detector signal in regard to the presence of the object ( ), its position, its shape and/or the temporal change of the position are performed.

Process and device for the detection of microscopically small objects

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

Electrode arrangement for the dielectrophoretic diversion of particles

To manipulate microparticles in a fluid that intersects a first channel or several first channels as a stream, one or more microparticles ( ) are exposed to electrical field barriers that change their direction from the direction of flow toward the edge of the flow to a lateral hole ( ) of the respective first channel. As a result, microparticles can be moved back and forth between streaming fluids. Preferred applications include treatment, separating, sorting or confinement procedures.

Method and device for manipulating microparticles in fluid flows

The aim of the invention is to convectively move at least one liquid in a channel of a microsystem which comprises a predetermined channel direction. To this end, the liquid is, in a partial section of the channel, subjected to an electric field gradient and optionally to a thermal gradient. The gradients are generated in the partial section corresponding to a predetermined field direction, whereby the field direction differs from the channel direction.

Method and device for the convective movement of liquids in microsystems

An electroporation and/or fusion treatment of microscopic objects occurs in a medium between at least two electrodes, with the electrodes being miniaturized electrodes in a microsystem with a channel structure which is set up for the flow-through of the medium with the objects.
