Abstract

Poly (amidoamine) (PAMAM) dendrimers are used to create organic-inorganic hybrid colloids in aqueous solution. The formation of gold colloids upon reduction of a gold salt precursor serves as a model reaction to study the influence of reaction conditions and dendrimer generation on the resulting nanostructures. The hybrid particles were characterized by transmission electron microscopy (TEM), small angle neutron scattering (SANS), and small angle x-ray scattering (SAXS). A transition is found from “colloid stabilization” by low molecular mass molecules to “polymer nanotemplating” with increasing dendrimer generation, i.e, increasing molecular mass but retaining the chemical nature of the stabilizing species.
