Abstract (en)

[origin: WO2004077034A1] The invention relates to a method for detecting interactions between two or more molecules by measuring the change in the luminescence decay period, especially the phosphorescence decay period of a luminophore fixed to at least one of the molecules. At least one interacting partner is marked with a luminophore having a decay period of at least 50 ns. A delay phase during which interfering background fluorescence is able to decay is provided after switching off the light pulse.
