    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.

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： The invention relates to a microelectronic sensor device and a method for the investigation of biological target substances (20), for example oligonucleotides like DNA fragments. In one embodiment, the device comprises a reaction surface (RS) to which target specific reactants (10) are attached and which lies between a sample chamber (SC) and an array of selectively controllable heating elements (HE). The temperature profile in the sample chamber (SC) can be controlled as desired to provide for example conditions for a PCR and/or for a controlled melting of hybridizations. The reactant (10) and/or the target substance (20) comprises a label (12) with an observable property, like fluorescence, that changes if the target substance (20) is bound to the reactant (10), said property being detected by an array of sensor elements, for example photosensors (SE). The fluorescence of the label (12) may preferably be transferred by FRET to a different fluorescent label (22) or quenched if the target substance (20) is bound.
