From Bubbles to CapsulesPosted on September 07, 2006
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. Japanese researchers have now developed a clever new technique for the production of silicon dioxide nanocapsules: they start with tiny bubbles of carbon dioxide in a silicon copolymer.
