    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.

    摘要: A detection system (100, 150) for qualitative or quantitative detection of a magnetic field property of a modulated magnetic field is described. The modulated magnetic field may e.g. stem from an adjacent electrical current (Iadj) or magnetic particles. The detection system (100, 150) comprises at least one magneto resistive sensor element (102), a current controller (104) for providing a sensing current (Isense) flowing through the magnetic sensor element (102) and a controlling means (108). The controlling means (108) is adapted for deriving at a first frequency f1 a temperature-related parameter of the at least one magneto resistive sensor. The controlling means (108) furthermore is adapted for deriving a qualitative or quantitative characteristic of the adjacent electrical current (Iadj) or magnetic particles, taking into account the derived temperature-related parameter. This second frequency (f1) is different from the first frequency (f1}). The invention also relates to a corresponding method.

    摘要: The invention relates to a microsensor device like a magnetic biosensor (100). The microsensor device comprises an array of probe-sensors (10.1, 10.2, 10.3) for the measurement of a physical quantity, for example the concentration of molecules labeled with magnetic beads in a sample chamber. The array further comprises a reference-sensor (10.4) that is disposed close to the probe-sensors (10.1, 10.2, 10.3) but shielded from the physical quantity to be measured. The measuring signal of the reference-sensor (10.4) reflects the influence of environmental conditions like temperature and can therefore be used to correct the measuring signals of the probe-sensors (10.1, 10.2, 10.3). The sensors (10.1, 10.2, 10.3, 10.4) are connected via a multiplexer to the same detector unit for further processing in order to minimize variations and to reduce hardware complexity.
