Template-Free Assembly of Polymer Nanocapsules Hollow polymer capsules of controlled sizes for controlled delivery of organic molecules consist essentially of homopolymers. The capsules may be prepared by a facile, single-step self-assembly of an amphiphilic polyacid and a dispersing homopolymer. Assembled structures may be prepared to be reversibly dissolved via pH variations, or may be stabilized...

Clay-Containing Thin Coatings As Carriers Of Small Molecules A film for the retention and controlled release of organic or inorganic molecules consists essentially of a phyllosilicate clay and a organic polyanion. The film may be a built-up layered film of alternating layers of the clay and the polyanion. Organic or inorganic molecules are absorbed into the film from solution, and released in response to changes...
