    摘要: A detection system (100) and a sensor chip (1) for detecting target molecules, and thus corresponding analytes in a sample is described. Typically the detection system (100) includes a sensor chip (1). The sensor chip (1) comprises on its detection surface (33) a dissolvable reagent layer (5). When the dissolvable reagent layer (5) is in contact with sample fluid, free reagent is generated, assisting in the interaction between a label and target molecules, thus allowing for label based detection. The sample thereby is exposed to mobile reagents in a burst. The reagent layer may contain an enzyme allowing enzymatic assays.

    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.
