Multilayered polymer nanocapsules derived from gold nanoparticle templates

Abstract

An area of chemical research involves the synthesis of polymeric capsules with well defined dimensions. The synthesis of hollow multilayered polymeric capsules formed by a layer-by-layer polymer adsorption process on gold templates is reported. The direct coating of particles with preformed polymers is an attractive means to achieve a uniform coating. Aqueous colloidal metals are stabilized by nonionic polymers. It is not possible to build up multilayer coatings on monolayer-coated particles. Spectrophotometric analysis provided the evidence for particle coating.
