6. The functional group that binds to the metal has a dramatic impact on the nanocrystal size. The binding must be strong enough to induce ligand sticking; however, binding must be sufficiently reversible to allow for particle growth. Various metals require a mixture of capping ligands to achieve these properties. For example, FePt nanocrystals require a mixture of oleic acid and oleylamine (ref 5) while Co nanocrystal growth requires a mixture of oleic acid and alkyl phosphines (ref 4).
