    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).

    摘要: A sensor device (1) for detecting the presence of a target molecule (20) in a sample, is disclosed. The sensor device comprises a measurement sensor (2) comprising a first moiety (16) for forming a binding couple with a first further moiety comprising the target molecule (20) and a detectable label (40) and a reference sensor (3) comprising a second moiety (50) for forming a further binding couple with a second further moiety comprising a further detectable label (40′). The sensor device is adapted to generate a first detection signal (14) from the detection of the detectable label (40) in the first further moiety bound to the first moiety (16) and to generate a second detection signal (14′) from the detection of the further detectable label (40′) in the second further moiety bound to the second moiety (50), wherein at least during operation of the sensor device the second further moiety is expected to be present in a predefined amount such that the value of the second detection signal (14′) falls within an expected signal value window when the binding reaction of the second further moiety to the second moiety takes place as expected. An apparatus comprising such a sensor device, methods of operating the sensor device and apparatus and a sample for use with the sensor device are also disclosed.

The magnetic sensor device comprises:—a sensor chamber (12) having a sensor surface (120), the sensor surface comprising a plurality of binding sites (121) adapted for binding magnetic or magnetizable objects; and—a magnetic field generating means (26) adapted for generating a magnetic field for inducing a movement of magnetic or magnetizable objects along the sensor surface (120), the magnetic fields having a magnetic field gradient across the sensor surface (120). The magnetic field gradient generated by the magnetic field generating means (26) in each of the centres of the plurality of binding sites (121) is substantially identical.
