The biosensor further comprises means for generating a magnetic field at the binding sites of the sensor surfaces of the at least two chambers. The biosensor also comprises means for detecting particles accumulated at/and or proximate the binding sites of the sensor surfaces of the at least two chambers. Therein, the magnetic field at the binding sites has a sufficiently large gradient to actuate magnetic label particles towards the binding sites.

摘要: A microfluidic reactor arrangement (100) for use in detecting an analyte in a fluid sample (106) is described. The reactor arrangement is provided with a reagent providing means such that the reagent can be introduced after assembly of the reactor arrangement. The latter can be performed by introducing the reagent in the form of a solution or a dispersion and fixing it on a holding means (118) by removal of the liquid, i.e. by drying, the holding means comprising the reagent in a solid version in the detector chamber. Prior to the introduction of the reagent, components of the reactor arrangement already present, such as the sample inlet can be hydrophilised by a wetting hydrophilising technique. The invention relates to a manufacturing technique as well as to the resulting product. The invention furthermore relates to functionalizing of the reactor arrangement with a particular reagent for particular applications. The latter can be performed well after fabrication and assembly of the major reactor arrangement components.

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.
