Sensor element for optically measuring fluorescence, and method of producing it

摘要

In order to increase the fluorescence yield, the receiving surface of a base is provided with protrusions which are distributed with uniform density and are formed by glued-on, fused-on or sintered-on particles which have a high specific surface and act as intermediate carriers for indicator material immobilised thereon. To reduce undesirable effects on the measurement result due to the properties of the sample, the microenvironment of the indicator molecules may be provided, by applying further substances, with defined properties.
