We are working toward fully integrated CMOS interface dedicated for cells manipulation and separation in LoC devices. The interface includes all microelectronics circuits for dielectrophoretic manipulation and capacitive detection. It contains also an embedded frequency and phase micro controller to ensure different type of cells displacements such as rotation, translation and separation with a wide tunable frequency band of 250 kHz for LoC applications. Furthermore, the detection part is a charge-based capacitive measurement circuit with a high sensitivity of 10 mV for each 1 fF. This new chip is part of a LoC device including both the microfluidic and the microelectronics chips.
