The invention relates to a microelectronic device (200), particularly a magnetic biosensor, comprising B/E-electrodes (21) that can generate a magnetic field (B) in a sample chamber (10). The device further comprises E-electrodes (23, 24) that can generate an electrical field (E) in the sample chamber (10) in cooperation with the B/E-electrodes (21). Thus the B/E-electrodes are used for two purposes. Electrical fields (E) in the sample chamber (10) may particularly be used for pumping and/or mixing of a fluid sample or for a stringency test of particle bindings.

The Invention concerns to a micro-actuator device for the use in biochip or bio-system. In order to achieve a micro-actuator device for the use as a micro pump in biosensors or bio-systems, or at least bio-chips, by which the actuation can be steered very precisely and effective, the solution is that the micro actuator consist of a photosensitive actuator element (1), which can be deformed from a reversal basic-form into an activated deformation form by photonic activation of a light source (3, 4, L1, L2) in order to generate with this controlled movement a defined flow in a gas or a liquid.

The invention relates to a microelectronic device, particularly a microelectronic biosensor, comprising an array of field electrodes (FE) for generating an alternating electrical field (E) in an adjacent sample chamber (SC). The field electrodes (FE) are coupled to associated local oscillators (OS), which are preferably tunable and connected in a matrix pattern to an external control unit (CU). The local oscillators (OS) allow high frequencies of the generated electrical fields (E), such that for example dielectrophoretic forces can be generated.

The invention relates to different designs of a microelectronic device comprising heating electrodes (HE) and field electrodes (FE) that have effect in the same sub-region of a sample chamber. By applying appropriate voltages to the field electrodes (FE), an electrical field (E) can be generated in the sample chamber. By applying appropriate currents to the heating electrodes (HE), the sample chamber can be heated according to a desired temperature profile. The heating electrodes (HE) may optionally be operated as field electrodes such that they generate an electrical field in the sample chamber, too.
