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： A substance determining apparatus determines a substance within a fluid where particles, which have attached the substance, are bound to a binding surface. A sensing unit is configured to generate a sensing signal being indicative of at least one of i) a distance between the particles bound on the binding surface and the binding surface, and ii) an in-plane position of the particles bound on the binding surface. A binding discrimination unit is configured to discriminate between different kinds of binding of the particles bound on the binding surface depending on the generated sensing signal. The binding discrimination unit may be a unit for determining the part of the sensing signal being caused by specifically bound particles and for determining the substance based on this determined part of the sensing signal.

摘要： 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.
