ABSTRACT:
Fluorescent measurements are taken utilizing a Raman enhancing surface by a method which allows reduction or essentially complete elimination of interference by fluorescence quenchers. In particular, the fluorescent medium to be measured is interacted with a Raman enhancing surface. Through this interaction between the Raman enhancing surface and the fluorescing species, fluorescence quenching is eliminated. The quenching is particularly significant in analytical procedures such as those involved in chromatography and medical testing.
