Designed for researchers and professionals, the text covers the development history and basic concept and knowledge of cell-based biosensors; cell culture on chips; the mechanism and models of cell-based biosensors; the microelectrode array as a cell-based biosensor designed for transferring and recording cellular action potential; the cell-based field-effect transistor sensor fabricated by semiconductor technology; proposal of a light addressable potentiometric sensor; the electric cell substrate impedance sensing; the patch clamp chip; other cell-based biosensors, such as quartz crystal microbalance, surface plasmon resonance, and immune cell-based biosensors; and developing trends.
In the syncytial structure, the input resistance can be measured by using double-microelectrode technique [1-3], when one barrel of the microelectrode is used for delivering a rectangular jump of current, and the other one is used for recording the intracellular potential.
