Abstract:
A device (100; 200; 300; 400; 500) for the detection of a fluorescent dye (F) in samples (P), comprisinga device (110; 210; 310; 410; 510) for exciting the fluorescent dye (F) to be detected, said device (110; 210; 310; 410; 510) comprising a detecting surface (112; 212; 312; 412; 512) provided for the application of samples (P) and an excitation light coupling device (111; 211; 311; 411; 511) by means of which a single excitation light from a predefined direction of impingement (R) can be coupled into the device (110; 210; 310; 410; 510) so that, by means of an evanescent field of the coupled light, the fluorescent dye (F) to be detected can be excited in the samples (P) applied, anda means (120; 220; 320; 420; 520) for the detection of the fluorescent light emitted by the fluorescent dye (F) to be detected,characterized in thatthe device for exciting the fluorescent dye (F) to be detected is a contigous light guiding layer, wherein the samples are placed on the detecting surface of the contiguous light guiding layer separately from each other and are excited contiguously by the single excitation light, the detecting surface being movable relative to the direction of impingement (R) so as to excite the fluorescent dye (F) to be detected in different subsections of said surface (112; 212; 312; 412; 512).
