Abstract

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.
