title: Self-assembled light-harvesting supercomplexes from fluorescent surface-cross-linked micelles.
abstract: Fluorescent nanoparticles made of cross-linked dansylated surfactants allowed efficient donor-donor energy migration within and beyond the nanoparticles when the nanoparticles aggregated in the presence of oppositely charged energy acceptors. The light-harvesting system enabled a single acceptor to quench the emission of over 500 donor chromophores.
