    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 present invention relates to a cartridge (1) for the detection of an analyte (2) in a binding assay with magnetic labels (3), the cartridge comprising at least one capture binding agent (4) against a binding site on the analyte and comprising at least two magnetically labelled tracer binding agents (51 and 52) against further different binding sites on the analyte, characterized in that the cartridge comprises at least two regions (61 and 62) wherein a first region (61) comprises the at least one capture binding agent (4) and a first magnetically labelled tracer binding agent (51) and wherein a second region (62) comprises at least one capture binding agent (4) and a second magnetically labelled tracer binding agent (52). Herein the first region (61) does not comprise a magnetically labelled tracer binding agent other than the first magnetically labelled tracer bind agent (51) and wherein the second region (62) does not comprise a magnetically labelled tracer binding agent other than the second magnetically labelled tracer binding agent (52).
