    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: The invention relates to a microelectronic sensor device for the detection of target components that comprise label particles, for example magnetic particles (1). The sensor device comprises a carrier (11) with a binding surface (12) at which target components can collect and optionally bind to specific capture elements. An input light beam (L1) is transmitted into the carrier and totally internally reflected at the binding surface (12). The amount of light in the output light beam (L2) and optionally also of fluorescence light emitted by target components at the binding surface is then detected by a light detector (31). Evanescent light generated during the total internal reflection is affected (absorbed, scattered) by target components and/or label particles (1) at the binding surface (12) and will therefore be missing in the output light beam (L2). This can be used to determine the amount of target components at the binding surface (12) from the amount of light in the output 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 15 attracted or repelled.

    摘要: The present invention relates to an optical system for performing radial tracking on an associated optical record carrier. The optical system contains at least one radiation-emitting device capable of emitting at least three beams: a first beam for reading and/or recording information, and at least a second beam and a third beam for tracking. The optical system is adapted for radial tracking of the first spot from a tracking error signal generated based on the high-frequency component of the central-aperture signal of the second and third beams. The tracking error signal may be generated based on a difference signal of a DC-level of the power of the high-frequency components of the central-aperture signal.

    摘要: The present invention relates to a sensing device (100) for detecting a target substance (2) in an investigation region (113). The sensing device (100) comprises a sensing surface (112) with an investigation region (113) and a reference region (120) thereon. The sensing device (100) further comprises a reference element (121) located at the reference region (120). The reference element (121) is adapted to shield the reference region (120) from the target substance (2) such that light reflected at the reference region (120) under total internal reflection conditions remains unaffected by the presence or absence of the target substance (2). This allows measuring a property, typically the intensity, of light reflected at the reference region (120) independent of the presence or absence of the target substance (2). This measured property of the reflected light can be used for performing an improved correction of light reflected at the investigation region (113).
