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.

The first surface (104) of the at least one optical component (102) is located to internally reflect incident excitation radiation to create an evanescent field outside the at least one optical component (102) for exciting the at least one sample (108). The detection system also comprises at least one detector element (110) that is in direct contact with the at least one optical component (102) to detect the luminescence from at least one excited sample (108) through the at least one optical component (102).

摘要: The invention relates to a substance determining apparatus (19) for determining a substance within a fluid. A location event determination unit (34) determines location events indicating that a particle, which may have attached the substance, is located in a sensing region and a property of the location events from the sensing signal generated by sensing the sensing region. A location events selection unit (70) selects a part of the location events having a property in a predefined property range, and a substance determination unit (40) determines the substance within the fluid (3) based on the selected part of the location events. This allows tuning the determination of the substance within the fluid to a desired property range, which can relate to a desired kind of bound particles, thereby reducing the influence of unwanted effects on the determination of the substance and, thus, improving the determination accuracy.
