摘要： A device has a planar optical waveguide, including a transparent carrier (40) and a wave-guiding layer (41), wherein the waveguide at least has a diffractive element (42) for coupling excitation radiation into the wave-guiding layer. Located on the wave-guiding layer is a further, tightly sealing layer (43) made from a material which, at least at the support surface, is transparent both to the excitation radiation and to the evanescently excited radiation at least to the penetration depth of the evanescent field, and which, for an analysis sample, has, at least in a partial region of the guided excitation radiation, a cavity (45) which is open to the upper side or a cavity (6) which is closed to the upper side and connected by means of an inlet channel (2) and an outlet channel (3). The depth of the cavity corresponds at least to the penetration depth of the evanescent field, and the diffractive element (42) is fully covered by the material of the layer (43) at least in the coupling-in region of the excitation radiation.

摘要： The invention relates to a planar ATR and evanescently exited luminescence optical sensor platform, consisting of a transducer and a recognition layer, wherein changes in the effective refractive index of the recognition layer are converted into a measurable variable in accordance with the integrated-optical light pointer principle. The invention relates also to the use of the method and to the method itself using the sensor platform, for example in label-free biosensory analysis.
