From Bubbles to Capsules

Nanocapsules are vessels with diameters in the nanometer range and very thin shells. They can store a tiny volume of liquid and can protect their cargo while transporting it through a foreign medium — such as a human blood vessel — without any loss. Further applications for nanocapsules include the encapsulation of scents, printer ink, and adhesives. Once at their destinations, the payloads are released by pressure or friction.
