Bristly spheres as capsules
Date:3/6/2009

ulting ensemble of cores is, as a whole, surrounded by a sufficiently dense layer of bristles, which acts as a shield toward additional particles.

Cores with an even smaller number of polymer bristles aggregate into extended curved layers that close themselves off into capsule-shaped vesicles. The walls of the vesicles consist of a monolayer of the bristly particles.

The polymer-coated spheres offer a new, simple method for the controlled production of superstructures. The vesicles could be used to encapsulate drugs, for example, as contrast agents, or as ordered liquid crystalline phases for the production of nanostructured hybrid materials.
