Detection of biologically active compounds

摘要

A probe comprises a supramolecular structure having a chemical or biological recognition moiety; a phosphorescent reporter label; and an effector which interacts with the label so that the probe alters its phosphorescent characteristics on recognition of a target. The phosphorescent reporter label may have an emission lifetime in the order of 1 mus to 10 ms and may be selected from phosphorescent tetrapyrrolic compounds and their metallocomplexes.
