Abstract

Fluorescing reference material is used for calibration purposes for improving the measurement accuracy of sensors, especially biosensors, which use fluorescence radiation for determination of signals, the sensors each comprising a waveguide having at least one wave propagation surface as assay, a reactant being supported on the surface, the reactant comprising a species of molecule and being bound to an analytical material within a test medium, the waveguide transmitting an output emission radiation signal when it receives a radiation access signal.
