Abstract :
We present the fabrication of cell-based biosensors with cell positioning capabilities, which contain ion-sensitive field-effect transistors (ISFETs) and integrated dielectrophoresis electrodes. Yeast cells and bacteria have been successfully positioned on the active area of the device. The ISFETs have shown good operating characteristics as pH sensors.
