    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 detection the presence of a target molecule in a sample, wherein the sample is contacted with a substrate, the substrate subsequently being washed in a wash step. In particular, the invention relates to a method of detecting the presence of a target molecule in a sample, the method comprising: (a) contacting the sample (37) with a substrate having immobilized thereon probe molecules that specifically binds to the target molecule; (b) washing the substrate (38) in a wash step by a wash fluid in order to remove or dilute unbound target molecules; (c) detect the presence of resultant binding complexes (39) on the substrate to determine whether the target molecule is present in the sample. The wash fluid being substantially refractive index matched to the substrate.

    摘要: A detection system (100, 150, 180, 200, 220, 250) for detecting luminescence from at least one sample (108) when excited by incident excitation radiation. Detecting luminescence may allow to detect, for example, biological, chemical or bio-chemical particles. The detection system (100, 150, 180, 200, 220, 250) comprising at least one optical component (102) with at least a first surface (104). 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).
