ABSTRACT
Much has been learned about the structure of organic films and interfaces, and techniques to prepare these films in a controlled way have been developed. These have been concerned mostly with planar systems, but there is no obvious reason why this knowledge cannot be transferred to curved interfaces, which would offer many advantages:
Having succeeded in coating colloids, there is an obvious next step: to template colloids by dissolving the core and thus obtaining hollow capsules. This route is discussed in the following, including the interesting properties and possible applications of these capsules.
