Abstract
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.
Claims24
A microelectronic device for manipulating a sample, comprising:
- a) a sample chamber (SC);
- b) an array of field electrodes (FE, FHE) with associated local oscillators (OS) for generating an alternating electrical field (E) in at least a said sub-region of the sample chamber (SC).
