The electronic structure of gold and silver nanoclusters stabilized by organic ligands can be understood quite well from the simple superatom model that accounts for the delocalized sp-electrons in the metal core. Forming in most cases the frontier orbitals of the nanoparticle, these electrons are responsible for low-energy optical transitions and much of the chemistry. Recent progress in understanding the structure as well as physical and chemical properties of this class of superatoms is reviewed, and a novel application of using atomically precise, functionalized thiol-stabilized gold nanoclusters for site-specific conjugation to enteroviruses is discussed.
