摘要： A sensing device (100) detects a target substance (2) in an investigation region (113). The sensing device (100) includes a sensing surface (112) with an investigation region (113) and a reference region (120). The sensing device (100) further includes 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 a correction of light reflected at the investigation region (113).

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).

摘要： A substance determining apparatus determines a substance within a fluid where particles, which have attached the substance, are bound to a binding surface. A sensing unit is configured to generate a sensing signal being indicative of at least one of i) a distance between the particles bound on the binding surface and the binding surface, and ii) an in-plane position of the particles bound on the binding surface. A binding discrimination unit is configured to discriminate between different kinds of binding of the particles bound on the binding surface depending on the generated sensing signal. The binding discrimination unit may be a unit for determining the part of the sensing signal being caused by specifically bound particles and for determining the substance based on this determined part of the sensing signal.

摘要： The invention relates to a substance determining apparatus for determining a substance within a fluid. Particles attach the substance and bind to a binding surface (30), wherein a sensing signal is generated depending on the bound particles. Binding events indicating a binding of a particle on the binding surface (30) are determined from the generated sensing signal, and the substance within the fluid is determined based on the determined binding events. During a procedure of determining a substance within a fluid, particles may bind to the binding surface and may leave the binding surface. Therefore, during this procedure a number of binding events can be determined being much larger than the number of bound particles. The determination of the substance within the fluid can therefore be based on a very large amount of data, thereby increasing the accuracy of determining the substance within the fluid.

摘要： The invention relates to a system and a method for the detection of target components (102) in a sample with the help of indicator particles (101) distributed in said sample. The distance (d) between indicator particles (101) and a contact surface (112) is determined after the target components could bind to the contact surface and/or the indicator particles. Thus it is possible to detect how many target components (102) are bound without a need for a binding between indicator particles (101) and contact surface (112). Optionally the indicator particles (101) can be affected by a modulated force, e.g. via an electromagnet (141). The determination of the distance (d) between indicator particles (101) and contact surface (112) may for example be achieved by frustrated total internal reflection, measurement of magnetic fields, or FRET.
