摘要： The invention relates to a method and associated apparatuses (100) for the detection of magnetic particles (MP) in a sample chamber (111). The method comprises the determination of a "particle-parameter" that is related to the amount of magnetic particles (MP) in a first detection region (P, C), the determination of a "cluster-parameter" that is related to the degree of clustering of magnetic particles (MP) in a second detection region (P, C), and the evaluation of the particle-parameter based on the cluster-parameter. Various apparatuses are disclosed that can be applied in said method. In one apparatus (100), a magnetic field (B) is generated in the sample chamber (111) in such a way that it has different inclinations in a first and second field region (P, C) and/or that it is oblique to the binding surface (112) in at least one field region. Magnetic particles (MP) are then detected in said first and second field region and/or in said at least one field region before and after a permanent switch-off of the inclined magnetic field. The resulting detection signals are related to each other to determine a cluster-parameter. In other embodiments, a cluster- parameter may be determined from light transmission measurements during the application of a magnetic field that is switched on and off.

摘要： The invention relates to a method and a sensor device(100) for evaluating an assay with a sample. During the assay, optical measurements are made at a sensing surface(112), and at least one "homogeneity-image" of the sensing surface(112) is generated. From this image, an "homogeneity-indicator" is determined for at least one region of interest, and the optical measurements are then evaluated in dependence on said indicator. The homogeneity-indicator may for example be a binary value which indicates if an inhomogeneity was detected or not. If an inhomogeneity was detected, all optical measurements may be rejected, only measurements for the involved region of interest may be rejected, or measurements for a selected sub-area of the involved region of interest(ROI) may be rejected.

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 method and a sensor device(100) that allow for the determination of geometrical properties like the position and/or area of at least one detection spot(153) on a contact surface(152), wherein said detection spot(153) has a height that is different from the height of the residual surface. The detection spot(153) may for example be a region coated with binding sites for target molecules. The localization of the detection spot(153) is achieved by illuminating the contact surface(152) with evanescent waves and by observing an output light beam(L2, L2') which is affected by an interaction between test particles(1), which cover the detection spot(153) and the contact surface(152), and said evanescent waves. The test particles may for example be magnetic particles(1) that are attracted to the contact surface(152) by magnetic forces, or they may be transported to the contact surface(152) by sedimentation. The location of the detection spot(153) may be determined at the end or at the beginning of an assay and be used during the evaluation of measurements.

摘要： The invention relates to a substance determining apparatus and method for determining a substance within a fluid. Particles attach to the substance and bind to a binding surface (30), wherein a particle release curve being indicative of a release of bound particles from the binding surface (30) is determined, and a part of the particle release curve caused by particles bound to the binding surface via a predefined kind of binding is determined based on the temporal behaviour of the particle release curve. The substance within the fluid is determined based on the part of the particle release curve. The substance can therefore be determined based on particles which are bound to the binding surface via a certain kind of binding, i.e. other kinds of binding substantially do not affect the determination of the substance, thereby improving the accuracy of determining the substance.

摘要： The invention relates to a method and a sensor device (100) for detecting particles (MP) that are bound to the binding surface (12) of a carrier (11). The sensor device (100) comprises a microscope (50) for imaging bound particles (MP)onto an image sensor (53). In order to increase the spatial resolution of the microscope(50), a displacement unit (60,70,80) is provided that can displace the carrier (11) relative to the image sensor (53). The distance of a bound particle (MP) from the binding surface (12) and/or its lateraldisplacement in reaction to forces can thus be determine with high accuracy. This allows to discriminate specific bindings of large magnetic particles (MP) that are bound to the binding surface (12) via smaller target particles from nonspecific direct bindings.

摘要： The invention relates to a method and a sensor device (100) for the detection of magnetic particles (1) bound to the binding surface (111) of a sample chamber (112), wherein said detection is made during and/or immediately after the action of an attractive magnetic field. Preferably, the attractive magnetic field (B) is preceded by a repulsive magnetic field (B) which removes unbound magnetic particles away from the binding surface (111). Due to the attractive magnetic field (B), bound magnetic particles (1) come closer to the binding surface (111), which increases the signal of surface specific detection techniques like frustrated total internal reflection. A further enhancement of the signal can be achieved by an attractive magnetic field that is parallel to the binding surface (111), thus inducing the generation of chains between unbound and bound magnetic particles.
