Not only is our body made of individual organs, our cells themselves are made of tiny organelles, a variety of separate compartments that fulfill different tasks. Such functional, nanostructured systems would also be useful for technical applications, such as biosensors, self-repairing materials, optoelectronic components, or nanocapsules.

To accurately transport pharmaceutical agents to their specific target organs or cell types, you need a good carrier: nanoscopic capsules with surface elements that can "recognize"Â the target in question could do the trick. To date, all methods for the production of such tiny capsules require preorganized structures or "molds"Â to shape hollow spheres and most methods require a lengthy, tedious synthetic or purification procedure.
