    Abstract: A sensing system comprises at least one fluidic channel (104) for providing at least one analyte (105) into at least one region of interest; at least one radiation transport system (501), for providing excitation radiation (103) for exciting analytes traversing the at least one region of interest; and a radiation collection system (301) for collecting any radiation signal emitted from the at least one region of interest. The at least one radiation transport system is adapted for providing excitation radiation comprising a plurality of excitation radiation intensity peaks (101, 102), whereby the distance between the excitation radiation intensity peaks is known. The sensing system comprises means (302, 303) for measurement of the speed of the at least one analyte within the fluidic channel (104), the means for measurement of speed comprising timing means (303) for obtaining the time between maxima in radiation signals emitted by the at least one analyte.

    Abstract: Sensor devices for quantifying luminescent targets are described herein. An example device comprises a light source for exciting the targets, thus generating luminescence signals and a detector for detecting these signals, resulting in a detected signal which comprises a desired signal originating from the targets and a background signal. It moreover comprises a bleaching device for bleaching of at least part of the sources generating the background signal and a processor configured to trigger the bleaching device to start bleaching, and to trigger the light source for exciting the remaining luminescent targets which are not bleached, and to trigger the detector for detecting the luminescence signal of the remaining luminescent targets, so as to generate a measurement signal representative for the quantification of the luminescent targets.

    Abstract: A sensor device for quantifying luminescent targets. The device comprises a light source for exciting the targets, thus generating luminescence signals, and a detector for detecting these signals of the targets in a cell, resulting in a detected signal comprising a desired signal and a background signal. The detector has a spatial cell resolution and/or a time resolution that is so high that only a limited number of targets will be present in the cell when measuring at low concentration and/or that only a limited number of targets add to the cell in between two measurements. A change in the number of targets in the cell can be observed in the detected signal. The device comprises a processor configured to distinguish the desired and the background signal, and to combine the detected signals of the different cells and/or moments in time, to quantify the targets.

    Abstract: An integrated fluorescence detector for detecting fluorescent particles is described. An example integrated fluorescence detector comprises a substrate, the substrate comprising an integrated detection element for detecting fluorescence radiation from fluorescent particles upon excitation of the particles with incident excitation radiation. The integrated fluorescence detector also comprises a sensing layer adapted for accommodating fluorescent particles to be sensed. The integrated fluorescence detector further comprises a photonics crystal layer arranged in between the sensing layer and the substrate, the photonics crystal layer comprising an absorption material designed such that the photonics crystal layer is configured for diffracting incident excitation radiation into a lateral direction in which the photonics crystal layer extends for incident excitation radiation having a wavelength within at least 10 nm of the predetermined excitation wavelength.
