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. Characterization of the hybrid particles by transmission electron microscopy (TEM), small angle neutron scattering (SANS), and small angle x-ray scattering (SAXS) was performed. 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 constant chemistry of the stabilizing species.
