| 摘要 |
The invention is related to a variable embodiment of a sensor platform based on a planar thin-film waveguide for the determination of one or more luminescences from one or more measurement areas on said sensor platform, comprising an optical film waveguide of different layers ("stratified waveguide") with a first optically transparent layer (a) on a second optically transparent layer (b) of lower refractive index than layer (a) and at least one grating structure for the incoupling of excitation light to the measurement areas or outcoupling of luminescence light from the measurement areas. The invention is also related to an optical system for luminescence determination and to an analytical system, comprising a sensor platform according to the invention, an optical system according to the invention, and supply means for contacting one or more samples with the measurement areas on the sensor platform. Further subjects of the invention are detection methods by luminescence detection, and the use of these methods. |
