Fig. 1. Schematic of the synthesis of metal nanoparticles within dendrimer templates. The composites are prepared by mixing of the dendrimer and metal ion, and subsequent chemical reduction. These materials can be immobilized on electrode surfaces where they serve as electrocatalysts or dissolved in essentially any solvent (after appropriate endgroup functionalization) as homogeneous catalysts for hydrogenation and other reactions.

II. BACKGROUND A. A Brief Retrospective on the Use of Polymers other than Dendrimers as Templates for Nanoparticle Growth Materials other than dendrimers have been used for nanoparticle templating in the past. Polymers with metal-ion affinities can be used to sequester metal ions into localized domains that are then reduced or reacted to form metallic (or semiconducting) nanostructures (6). Block copolymers often serve this purpose, forming inverse micelle-like domains. A wide range of metal particles may be formed
