    摘要: The invention relates to a method and a device (100) for determining the amount of a target component (2) in a sample, wherein magnetic particles (2) can bind to a contact surface (4) with kinetics that depend on the sample-amount of the target component. The method comprises at least two washing steps during which magnetic particles (2) are magnetically moved away from the contact surface (4) and corresponding measurements of the remaining amount of magnetic particles (2) at the contact surface (4). The amount of target component in the sample is estimated from at least one of such measurement results. The measurement allows to determine also high concentrations of target component for which the sensor surface (4) is saturated in a steady-state.

    摘要: The invention relates to a sensor device (100) and a method for the detection of magnetic particles (1) in a sample chamber (2) with a contact surface (11). The sensor device (100) comprises a sensor unit (120, 130) for detecting magnetic particles (1) in a target region (TR) and/or in at least one reference region on the contact surface. Moreover, it comprises a magnetic field generator (140) for generating a magnetic field that shall guide magnetic particles to the contact surface. With the help of these components, an “auxiliary parameter” is determined that is related to the magnetic particles (1) and/or their movement but that is independent of binding processes taking place in the target region between magnetic particles and the contact surface. The auxiliary parameter may for example be related to the degree of mismatch between the positions reached by the magnetic particles (1) under the influence of a magnetic field and the target region (TR). The evaluation results can be used to validate and/or correct the measurements obtained in the target region (TR).

    摘要: The invention relates to a method and a system (100) for selectively processing a sample (130) according to one of a plurality of different assays, for example for detecting a certain target component in the sample. The system comprises a plurality of “specific reagent reservoirs” (120) that contain different sets of reagents, wherein each set is required for one of the assays. Moreover, the system (100) comprises a “universal reagent reservoir” in which reagents for several assays are provided, preferably reagents for all assays. The universal reagent reservoir may preferably be a cartridge (110) in which the processing of a sample (130) can take place and which comprises a plurality of binding sites that are selective for different target components. Depending on the assay to be performed with a sample (130) at hand, the appropriate specific reagent reservoir (121b) is chosen and processed in the universal cartridge (110). This can particularly be done by a manipulator (140) in a high-throughput automated laboratory system.

    摘要: The invention relates to a substance determining apparatus and method for determining a substance within a fluid. Particles attach to the substance and bind to a binding surface (30), wherein a particle release curve being indicative of a release of bound particles from the binding surface (30) is determined, and a part of the particle release curve caused by particles bound to the binding surface via a predefined kind of binding is determined based on the temporal behaviour of the particle release curve. The substance within the fluid is determined based on the part of the particle release curve. The substance can therefore be determined based on particles which are bound to the binding surface via a certain kind of binding, i.e. other kinds of binding substantially do not affect the determination of the substance, thereby improving the accuracy of determining the substance.
