    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 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: The present invention provides a sensor device (20) and a method for determining the presence and/or amount of target moieties (22) in a sample fluid (27), the target moieties (22) being labeled with magnetic or magnetizable objects (23). The sensor device (20) comprises a magnetic field generating means adapted for applying a retention field for retaining the labeled target moieties (22, 23) to the sensor surface (24) during fluid manipulations. Through this the binding between the labeled target moieties (22, 23) and the sensor surface (24) and/or the magnetic particles (23) and the target moieties (22) is substantially not disturbed during these fluid manipulations. This leads to a reliable and accurate sensor device (20).

    摘要: The invention relates to an apparatus (300) and a method for the separation of magnetic particles (1, 2) according to their properties, particularly their magnetic susceptibility. The apparatus comprises a magnetic field generator (320) with which magnetic actuation forces (Fm) can be exerted on the magnetic particles (1, 2) that affect a prevailing movement of the particles (1, 2), said movement being caused by non-magnetic influences, e.g. thermal energy or viscous drag (Fh). The magnetic field generator may for example comprise: (i) a wire (321) that crosses the flow of a sample fluid with varying inclination (α); (ii) wires that generate a local minimum of a magnetic potential from which different particles escape by Brownian motion with different rates; or (iii) pairs of particle-attracting wires for which the attraction of one wire is temporarily interrupted to allow the fastest magnetic particles to escape.
