Abstract: The application relates to a method and a microelectronic sensor device for making optical examinations in an investigation region (13) at the contact surface (12) of a carrier (10), wherein an input light beam (L1, L1?) is sent from a light source (20) towards the investigation region (13), and wherein an output light beam (L2, L2?) coming from the investigation region (13) is detected by a light detector (30). An evaluation unit (50) that is coupled to the light detector (30) is adapted to determine the wetting grade of the investigation region (13) based on a characteristic parameter of the output light beam (L2, L2?), e.g. its intensity. In a preferred embodiment, the evaluation unit (50) is adapted to determine a change in the light intensity caused by a liquid contacting the contact surface (12). The wetting grade may particularly be detected in a test region (14) that is located adjacent to the investigation region (13) and that has a higher roughness than the investigation region (13).

Abstract: A system and method is described wherein components of the reagent (4), e.g. labelled antibodies, are separated from the biologically active sensor surface (5) by depositing the reagent (4) on a carrier surface (3) distinct from the sensor surface (5) in the detection region (2), e.g. detection chamber. In this way, a high assay reproducibility is obtained. By allowing a short, well-defined and controlled, pre-incubation time between the particles of interest, e.g. drugs, in the sample fluid (20) and the reagent (4), the reproducibility will be increased, whereas the speed of the assay is guaranteed by having all components in one detection region (2), e.g. detection chamber.

Abstract: 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.

Abstract: Embodiments of the invention relates to a temperature sensor and an analytical device comprising the same. The temperature sensor comprises a carrier (11) with a detection surface (12) on which temperature indicating agents (14) are present and, optionally, at which target components can collect and optionally bind to specific capture elements. An incident light beam (L1) is transmitted into the carrier and evanescent wave excitation is induced at the detection surface (12). The amount of light in the reflected light beam (L2) or an optical, e.g. luminescence response is then detected by a light detector (31). In one example, evanescent light is affected (absorbed, scattered) by temperature indicating agents and optionally target components and/or label particles at the binding surface (12) and will therefore be missing in a frustrated total internal reflected light beam (L2).

Abstract: The invention relates to a sensor device (100) and a method for the determination of the amount of target particles (1) at a contact surface (112) adjacent to a sample chamber (2). Target particles (1) in the sample chamber are detected by a sensor element (SE) and at least one corresponding sensor-signal (s, s?) is provided. An evaluation unit (EU) then determines the amount of target particles (1) in a first zone (Z1) immediately at the contracts surface (112) and a second zone (Z2) a distance (z) away from the contact surface based on this sensor-signal. In an optical measurement approach, frustrated total internal reflection taking place under different operating conditions (e.g. wavelength, angle of incidence) may be used to extract information about the first and second zones (Z1, Z2). In a magnetic measurement approach, different magnetic excitation fields may be used to excite magnetic target particles differently in the first and second zone (Z2).

Abstract: Detecting magnetized or magnetizable target components in a fluid containing the magnetized or magnetizable target components amongst other magnetized or magnetizable components, uses a magnetic field generator (M1, 28) to attract the magnetized or magnetizable components towards a binding surface. A magnetic field controller (C1) applies the magnetic field to concentrate the magnetized or magnetizable components in columns on the binding surface, subsequently reduces the magnetic field to enable the columns to collapse, to allow more components to reach the binding surface, and reapplies the magnetic field so as to cause other components to be pulled off the binding surface to reform columns based on the bound target components. A surface sensitive sensor (S1, 26, 29) detects the bound magnetized or magnetizable target components.

This way, optical read-out and electrical functions, e.g. read-out, are combined in a single substrate, in a simple and cheap manner. Also a method of fabricating such sensor cartridge is provided.

Abstract: 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.

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 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.
