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. |
