    摘要： A method is disclosed for calibrating a sensor element, which has an immobilized probe oligonucleotide, via which the bonding of a target nucleic acid (Z) can be detected by the sensor. In at least one embodiment, the method includes: a) bringing the sensor element into contact with a control nucleic acid (K), the melting temperature Tm(K) of which is less than the melting temperature Tm(Z) of the target nucleic acid (Z); b) hybridizing the control nucleic acid (K) to the probe oligonucleotide at a temperature T[p] Tm(K) and detecting a negative control signal at a temperature T[n]. According to a refinement of at least one embodiment of the invention, a measuring signal of the target nucleic acid (Z) is measured at a measuring temperature T [mess], where Tm(K)

    摘要： An embodiment relates to a method and to an array for detecting live circulating or disseminated cells in body fluids (for example blood, urine) or tissue samples (for example bone marrow) mixed with liquid. The method includes: a) filtering the liquid sample through a porous membrane that is suitable for retaining cells to be detected, such that cells to be detected come to rest upon at least a part of the surface of the membrane and the sample liquid passes the membrane; b) applying a first process liquid containing a first agent for marking the cells to be detected with a first marker; c) incubating the process liquid on the membrane for a predetermined time period, wherein the cells to be detected are marked; and d) detecting the marked cells to be detected on the surface of the membrane.

    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.
