Chemists at UCLA have created the first reversible nano-valve: a molecular machine that they can open and close like a faucet whenever they want. Among the many potential applications are nanoscale drug delivery systems that could release pharmaceuticals at very precise points within the body, or even within a single cell.
(I-Newswire) - be used in molecular electronics.
The development of the new valve was supported by a Nanotechnology Interdisciplinary Research Team Grant from the National Science Foundation. Zink, Stoddart and their coworkers published their results in the July 8, 2005, online edition of The Proceedings of the National Academy of Sciences, and in the July 19, 2005, print edition of that journal.
