Abstract

General aspects of immunological analyses are reported and the application of some lanthanide complexes in fluoroimmunoassays is discussed. The photophysical properties of the complexes of cage-type ligands, which, up to now, showed the most intense metal luminescence are reported. The luminescence intensity of these complexes is discussed considering the efficiency of the incident light/emitted light conversion, defined as the product of the absorption efficiency of the ligand and the metal luminescence quantum yield upon excitation in the ligand. It is illustrated how the luminescence intensity can be enhanced by adapting the ligands on basis of the previously obtained results.
