    Abstract: 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.

    Abstract: A method for controlling the movement of magnetic or magnetizable objects (10) in a biosensor cartridge. The method comprises the step of providing a biosensor cartridge with a laterally extending sensor surface (A) and at least a magnetic field generating means (20, 30, 30') for generating a magnetic field with a field gradient substantially perpendicular to the sensor surface(A). The magnetic field generating means (20, 30, 30') are alternatingly actuated such that the generated magnetic field directs alternatingly the magnetic or magnetizable objects (10) substantially perpendicular to the sensor surface (A) away and toward the sensor surface, wherein pulse lengths of the alternating actuation are adjusted such that a lateral movement of magnetizable objects along the laterally extending sensor surface is substantially avoided.

    Abstract: The present invention relates to a sensing device (100) for detecting a target substance (2) in an investigation region (113). The sensing device (100) comprises a sensing surface (112) with an investigation region (113) and a reference region (120) thereon. The sensing device (100) further comprises a reference element (121) located at the reference region (120). The reference element (121) is adapted to shield the reference region (120) from the target substance (2) such that light reflected at the reference region (120) under total internal reflection conditions remains unaffected by the presence or absence of the target substance (2). This allows measuring a property, typically the intensity, of light reflected at the reference region (120) independent of the presence or absence of the target substance (2). This measured property of the reflected light can be used for performing an improved correction of light reflected at the investigation region (113).
