  • Publication number: 20130224762
    Abstract: Specific labeling of cells enables magnetic cell detection. The cell type to be detected is labeled, magnetic labels being bound to epitopes of a first cell-specific epitope type via antibodies of a first antibody type. Additionally, second/further magnetic labels are bound to epitopes of a second cell-specific epitope type on the cells via antibodies of a second antibody type, or the magnetic labels are bound to the antibodies of the first antibody type via antibodies of another antibody type and the antibodies of the first antibody type are bound to the epitopes of the first cell-specific epitope type on the cells.

  • Publication number: 20130164777
    Abstract: The disclosure relates to flow cytometry. A method for precise individual cell detection and cell measurement of cells in the flow is disclosed. A pair of magnetoresistive components are used to produce a characteristic measuring signal profile from which the following information can be obtained: number of measurement deviations, measurement deviation distances, measurement deviation amplitudes, measurement deviation direction and measurement deviation direction sequence. The flow speed and the cell diameter can also be determined.

  • Publication number: 20130102067
    Abstract: A device for monitoring test cells has at least one receiving unit for the test cells and a first measuring unit for cell measurement. With a second measuring unit, which has a light source and a scattered light detector, cell monitoring can be carried out during the cell measurement. For this purpose the receiving unit has an at least partially light-permeable substrate and is arranged between the light source and scattered light detector such that at least a part of the light generated by the light source shines on the receiving unit, is scattered on the test cells and, after leaving the receiving unit through the substrate, impinges on the scattered light detector.

  • Publication number: 20130004982
    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.

  • Publication number: 20120187938
    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.

  • Publication number: 20120182007
    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.

  • Publication number: 20120121067
    Abstract: An x-ray detector that is suitable for both imaging and dose rate measurement has a hybrid photoactive layer arranged between an electrode and a substrate. The hybrid photoactive layer includes a number of scintillators as well as a bulk heterojunction and is designed to produce indirect x-ray conversion. The bulk heterojunction absorbs the scintillator radiation to form electron-hole pairs that are detected electrically. The production takes place by a spraying process, in particular a co-spraying process of bulk heterojunction solution and scintillator particle suspension.

  • Publication number: 20120115179
    Abstract: A flexible, thin, elongated band is used as a substrate. Similarly to a magnetic tape, the band is unwound from a feed reel and is transported past an outlet opening of a receptacle containing the cells such that the cells are poured onto the band. Subsequently, the band containing the cells applied thereon is wound onto a take-up reel. The take-up reel is fixed on a drive shaft which can be rotated by a drive mechanism. The rotation thus achieved has the effect that the band is unwound, transported past the outlet opening and finally wound up. In addition, spacers are provided at the upper surface of the band in order to prevent the contacting of radially adjacent sections of the band containing the cells in a wound-up state.

  • Publication number: 20110024734
    Abstract: The embodiments relate to a device and a method for spraying coatings of organic construction elements. The embodiments relate, in particular, to the spraying of coatings made up of components that do not dissolve in the same solvent, for example, and/or the spraying of a plurality of coatings one after the other. A plurality of spray heads is used, for example one after the other and/or next to one another.
