    摘要: 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). This can be used to determine the temperature of the detection area and optionally the amount of target components at the binding surface (12) from the amount of light in the reflected light beam (L2, L2a, L2b). A magnetic field generator (41) is optionally used to generate a magnetic field (B) at the binding surface (12) by which magnetic label particles (1) can be manipulated, for example attracted or repelled.

    摘要: 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. The reapplication of the magnetic field acts as a magnetic washing step to release unwanted aspecific adsorption binding, leaving the targets, to improve sensitivity with simplified hardware and a reduction in cost and size.

    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.
