Abstract: A luminescence sensor, comprising a non-transparent substrate structure (2) having at least one aperture (5) intended to comprise an analyte and a transparent substrate structure (3), which is arranged to or adjacent said first structure (2). The aperture has a smallest lateral dimension, which is smaller than half the effective wavelength of an excitation radiation, such as light at a wavelength of 700 nm, resulting in an effective wavelength in water of about 538 nm. The transparent structure has a trench (4) with a surface portion provided with ligands with an affinity towards a target molecule. The trench results in that a luminophore attached to the target molecule will be positioned at the entrance surface of the aperture, where the excitation energy is largest.

Abstract: A device for monitoring radiation emitted by luminophores present in an analyte fluid of a wiregrid biosensor. The monitoring device comprises a non-polarized light source (41) for illuminating the wiregrid biosensor for exciting fluorescent labels arranged in the analyte fluid of said biosensor. A detector (71) detects radiation emitted by the labels after excitation. A polarizing filter (53) is arranged in between the transparent substrate and the detector for suppression of background emission radiation from labels positioned outside apertures in the wiregrid, in the analyte fluid.

Abstract: A method and sensor for the detection of luminescence radiation generated by at least one luminophore is disclosed.

Abstract: The present invention relates to a process for conducting real-time PCR, and to a device for conducting the method of the present invention. The invention is especially suited for the simultaneous identification and quantification of nucleic acids present in a sample, e.g. a biological sample. Further, this invention describes a method for simultaneous quantitative analysis of multiple nucleic acid sequences in a single compartment by using an integrated nucleic acid microarray combined with a highly surface-specific readout device. The invention relates to a device wherein a surface which is either part of the chamber surface or a surface that is created in the reaction chamber, such as bead surface, is coated with capture probes and in the same chamber, a PCR reaction takes place.
