    摘要: The invention relates to a method and an apparatus (100) for the enrichment of magnetic particles (1) in a sample fluid. The sample fluid is provided in a sample cartridge (2) between a first pole (111) and a second pole (112) of an actuator magnet (110). A minimal magnetic flux as well as a minimal magnetic gradient are then established inside the sample fluid, wherein their values depend on the particular magnetic particles (1) and the sample fluid under consideration. In a preferred embodiment, the first pole (111) has a single tip (T).

    摘要: A sensor device for detecting one or more magnetic particles (102) in a sample fluid is described. The sensor device (100) uses at least one rotating magnetic field generator (108) for applying a rotating magnetic field to the sample and more particularly the one or more magnetic particles (102) incorporated therein. The sensor device also comprises a controller for controlling the magnetic field generator such that the rotating frequency of the applied magnetic field is substantially larger than the critical slipping frequency for the magnetic particle. The effect of the induced rotation is sensed using a sensor element (112). Presence, amount and binding properties of the magnetic particles (102) may be derived from the measured effect. Alternatively or additionally the viscosity of the sample fluid may be determined.

    摘要: The present invention provides a sensor cartridge (10) for distinctively determining at least two different target moieties in a fluid sample. The sensor cartridge (10) comprises a reaction chamber (1) and at least a first and second region (2, 3) distinct from each other. The first region (2) comprises magnetic or magnetizable objects (4a) labelled with a first type of probes for specifically binding a first type of target moieties and the second region (3) comprises magnetic or magnetizable objects (4b) labelled with a second type of probes for specifically binding a second type of target moieties, the magnetic or magnetizable objects (4a, 4b) in the first and second region (2, 3) being directly contactable by the sample fluid. The present invention also provides a method for the manufacturing of such sensor devices (10) and a method for determining the presence and/or amount of at least two different target moieties in a sample fluid using such sensor cartridge (10).
