ABSTRACT:
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.
