Abstract:
1. A method of making a functionalized nanostructure, the method comprising: providing a nanostructure comprising a substantially water-insoluble first polymer that comprises neutral functional groups without ionizable hydrogen atoms on its surface, the nanostructure also having a transverse dimension less than 1000 nm; reacting at least some of the neutral functional groups with a reagent under conditions and for a time sufficient so as to convert at least some of the neutral functional groups to converted functional groups, wherein the converted functional groups comprise one or more anions, ionizable hydrogen atoms, or a mixture of anions and ionizable hydrogen atoms, thereby generating a functionalized nanostructure; and contacting the functionalized nanostructure with a metal hydroxide or a second polymer under conditions and for a time sufficient to deposit a metal oxide coating or to deposit a coating of the second polymer onto the functionalized nanostructure.
