    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 present invention provides a method of measuring the concentration of molecules in a sample fluid or analyte. Said method comprises the step of mixing the fluid with label particles within a cartridge, wherein the label particles are adapted to capture said molecules and to bind to a sensor surface of said cartridge. Then, the label particles are sedimented towards the sensor surface and the amount of label particles close to the sensor surface is measured. Subsequently, the label particles, which are not bound to the surface, are removed in a “washing” step and finally the amount of label particles close to the sensor surface is measured again.

    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.
