Abstract
The present technology relates to luminescent lanthanide complexes comprising a chelating agent, formed of a macrocycle or ligand, complexing a lanthanide ion Ln3+ selected from terbium and dysprosium, the chelating agent comprising at least one group of the structure (B) below; and a process for detecting a biomolecule using said lanthanide complex comprising coupling a luminescent lanthanide complex of the present technology having a reactive group with said biomolecule.
