    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： A luminescence sensor, such as a luminescence biosensor or a luminescence chemical sensor, includes a substrate having at least one aperture filled with a medium. The aperture has a first lateral dimension larger than the diffraction limit of excitation radiation in the medium, and a second lateral dimension smaller than the diffraction limit of the excitation radiation in the medium. A method is also provided for the detection of luminescence radiation, e.g. fluorescence radiation, generated by at least one optically variable molecule, e.g. fluorophore, in the at least one aperture. Beneficially, the excitation radiation is polarized to suppress the excitation radiation in the apertures. The luminescence sensor and the method are able to detect relatively low concentrations of optically variable molecules, e.g. fluorophores.

    摘要： The present invention provides a luminescence sensor (2), such as e.g. a luminescence biosensor, comprising a multi-layer structure. The multi-layer structure comprises at least a first layer (2a) formed of a first material and a second layer (2b) formed of a second material. The first material has a first binding capacity towards luminophores and the second material has a second binding capacity towards luminophores, the first binding capacity being different from the second binding capacity. The luminescence sensor (2) according to the present invention shows a high sensitivity because it provides preferred binding sites for luminophores at locations where the combined excitation and detection efficiency is the highest.

    摘要： The invention relates to an optical system that particularly allows an improved detection of signal light propagating from a light source (1) through a flat glass substrate (11). SC-modes of this signal light that would normally be totally internally reflected at the backside (10) of the substrate (11) are coupled out by a first diffractive optical element DOE (21). To map all signal light leaving the substrate (11) onto a single target location (51), a focusing lens (31) and a second DOE (41) are disposed in the optical path behind the substrate (11). The DOEs (21, 41) may for example be a ID sinusoidal grating or a 2D blaze grating. The optical system may particularly be applied in an investigation apparatus for detecting multiple spots of a fluorescent sample material.
