The synthesis of fluorescent H2O-sol. Au nanoparticles by the redn. of a Au salt in the presence of a designed polymer ligand is described, the size and fluorescence of the particles being controlled by the polymer to Au ratio; the most fluorescent nanomaterial has a 3% quantum yield, a 1.1 nm Au core and a 6.9 nm hydrodynamic radius.
