    摘要: A sensor arrangement including a control circuit is disclosed. In at least one embodiment, at least one sensor electrode can be charged and/or discharged therewith and a comparator unit for the comparison of a provided voltage for the at least one electrode with a reference voltage. A duration necessary for the charging/discharging of the at least one sensor electrode is determined, whereby, from the determined duration, it is determined whether a sensor event, in the form of a hybridisation between trap molecules and the particles for recording, has occurred.

    摘要: A sensor element is for detecting DNA single strands which are possibly contained in an analyte. The sensor element includes a substrate and at least two electrodes in and/or on the substrate. In a surface area of the substrate, catcher molecules are immobilized and are adapted to hybridize to DNA single strands that are possibly contained in an analyte. The DNA single strands include a label that has dielectric properties that are different from those of the analyte. The electrodes are coupled to a detection device for detecting a change in the capacitative portion of the impedance between the electrodes due to a label that is present in an area surrounding the electrodes as a result of the hybridization event.

    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.
