    摘要: A process concentrates nucleic acid molecules to be detected of a sample on a surface, with capture molecules that specifically bind the nucleic acid molecules. A support material has a capture probe that can specifically be linked to the nucleic acid molecules to be detected to give complexes. The support material and the nucleic acid molecules of the sample are incubated to form the complexes. The complexes are moved to the surface. At least one portion of the complexes becomes bound to the capture molecules via the capture probe.

    摘要: Disclosed is an apparatus that is used for detecting liquids or substances from liquids and includes a plunger that has a porous plunger layer which is pressed onto a sensor array. Each sensor of the sensor array is surrounded by elevations which spatially separate the sensors from each other like walls. In at least one embodiment, when the plunger layer is pressed onto the sensor array, the walls are pressed into the pores of the plunger layer. Liquid-tight connections are created between the walls and the plunger layer while liquid remains over the sensors. The liquid can be measured. In at least one embodiment, when there is direct mechanical contact between the plunger layer and the sensors, the liquid over the sensors is located in open pores on the surface of the plunger layer. No liquid flows between the pores and across the walls when pressure is applied to the plunger layer such that closed reaction chambers are created.

    摘要: The single nucleotide polymorphism analysis involves the utilization of a DNA hybridization process as well as the use of a DNA chip. A liquid DNA sample to be analyzed is guided over a DNA chip in a defined time course. After successful hybridization, the temperature is modified in a defined manner under low stringency conditions such that scavenger/target DNA hybrids are melted, whereby the melting of the scavenger/target DNA hybrids is detected and evaluated according to the temperature. In addition to the DNA chip, at least one device is provided that controls and regulates the temperature, and another device is provided that controls a lateral flow of liquid against the surface of the DNA chip. Factors for matching hybrids and mismatching/single point mismatching hybrids can be detected and evaluated using appropriate measuring device(s).

    摘要: Electrochemical transducer arrays are already known from the prior art. According to the invention, the transducer array is provided with at least one flexible, planar metal substrate on which at least one flexible insulator having a firm connection between the metal surface and the insulator surface is disposed. The metal substrate and the insulator disposed thereon are structured in such a manner as to give metal areas which are electrically insulated the one from the other and which serve as sensor areas. The metal substrate used is self-contained so that the structured metal areas can be contacted from the lower side.

    摘要: A PCR process for DNA amplification with thermocyclisation of the corresponding reagents is disclosed, in which total integration of all substances and process steps is achieved in a closed, single-use unit (so-called cartridge) in which the reagents are stored in a storage-stable form at room temperature. According to the process, the water-soluble reagents are covered by a water-insoluble medium, then the DNA to be amplified is supplied and the water-insoluble medium is eliminated, so that the water-soluble reagents are dissolved and PCR can start. In the corresponding arrangement, a test unit designed as a single-use produce (a so-called cartridge) has at least one micro-channel or micro-cavity for receiving a PCR reagent. The PCR reagents in the form of a mixture which can be dried at a negligible vapour pressure and forms a storage-stable substance substance at room temperature adhere to the walls of the micro-channel or micro-cavity and form a thin film covered by an insoluble medium.
