Abstract: A magnetic flow cytometry apparatus for detection of cells labeled with magnetic nanoparticles has at least one pair of oppositely oriented magnets to provide between the magnets a first magnetic field region with a low magnetic field strength and to provide at poles of the magnets second magnetic field regions with a high magnetic field strength. The magnetic labeled cells provided within a flow input into the magnetic flow cytometry apparatus are enriched in at least one of the second magnetic field regions and supplied to the first magnetic field region, where a magnetic field is applied to the enriched magnetic labeled cells to measure the magnetic relaxation of the magnetic labeled cells in response to the applied magnetic field.

Abstract: A device and a method are disclosed for the detection and/or for the quantification of an analyte. In at least one embodiment, the device includes a basic matrix and magnetized nanoparticles, which are arranged in moveable fashion in or at the basic matrix and to which catcher molecules that bind specifically to the analyte are anchored. Further, the mobility of the nanoparticle in the basic matrix can be influenced by a binding of the analyte to be detected to the catcher molecules and can be read out magnetically.

Abstract: A flow cytometer has a flow chamber in which labeled cells are highly likely to be detected by a corresponding sensor as a medium carrying the magnetically labeled cells flows through the flow chamber. The flow chamber has at least one sensor positioned on an inner surface thereof to detect the cells. The flow chamber also has a magnetic or magnetizable cell guiding device which can be positioned upstream of the sensor in the direction of flow to guide the flowing, magnetically labeled cells directly across the sensor, so that only a small percentage of labeled cells pass outside of the reach of the sensor.

Abstract: Magnetically labeled cells in a flow chamber cytometer are detected by a GMR sensor. The flow chamber includes a cell guiding device having at least one first and one second magnetic or magnetizable flow strip. The flow strips, which serve to guide the flowing cells across the sensor in a target-oriented manner, are mounted at a distance from each other such that a magnetic field BF is produced between them. The GMR sensor is arranged in the region of the magnetic field BF between the flow strips such that the magnetic field BF can be used as the operating magnetic field BGMR of the GMR sensor. In this way, the need for additional magnets for operating the GMR sensor is eliminated.

Abstract: The invention relates to a probe for electrical measurements and use of a flexible probe to produce an inflexible probe. Conventional probes comprise a substrate which is mechanically rigid. As a result only planar surfaces may be examined with the probe. According to the invention, a probe is flexibly embodied by means of a flexible substrate such that the probe may be adjusted to match various curvature radii of test bodies.

Abstract: When using a rigid substrate eddy current probe to measure a non-planer test piece, the probe must be adapted to the test piece shape in order to avoid incorrect measurement values. Disclosed is a probe which is configured in a flexible manner via a flexible substrate so as to be adjustable to different radii of curvature of a test piece. Furthermore the probe lining is also embodied in an elastic manner.

Abstract: A scanning head for eddy-current testing includes a probe coil configuration disposed on a film on a film base. The film base is matched to a shape of an object to be tested. This allows quick, low-interference eddy-current testing. A method for producing a scanning head for an eddy-current test and an eddy-current test method are also provided.
