Single cell measurement using the portable impedance analyzer

This paper presents the development and application of a miniaturized impedance sensing system for a single cell impedance measurement. The system includes a set of plane electrodes on a biochip, a function generator, an impedance analyzer and a handheld microscope. The system also equips a programmable controller for the automatic impedance measurement and analysis. It can execute the cell located and cell measured by effects of dielectrophoresis (DEP) and alternating electrothermal (ACET).
