摘要：
A DNA chip includes a carrier and a microarray of spots containing immobilised catcher molecules which are arranged on the carrier. Each spot contains a microelectrode system for the impedance spectroscopic detection of binding events occurring between the catcher molecules and target molecules of an analyte solution applied to the spots. The microelectrode system has a pair of polarisation electrodes in order to produce an alternating electromagnetic field and a pair of sensor electrodes for measuring a voltage drop in the analyte.
