On the dot : Efficient energy transfer from Tb complexes to quantum dots with an extremely large Förster radius of 81 Å is achieved by formation of a streptavidin–biotin coupled donor–acceptor complex. The long luminescence lifetime of the Tb donor and the high absorption of the quantum dots make this couple a powerful tool for analyzing biological and biochemical interactions.
