Abstract
A method for producing a composite nanoparticle, including the steps of, collapsing at least a portion of a polyelectrolyte polymer in solution about one or more precursor moieties to form a composite precursor moiety having a mean diameter in the range between about 1 nm and about 100 nm, wherein the polyelectrolyte polymer has an extended conformation in a first solution state and a more compact conformation in a second solution state; and cross-linking the polyelectrolyte polymer of the composite precursor moiety to form a composite nanoparticle wherein the precursory moiety is a charged organic ion.
