Mr. Otis, Call Your Office: A Nano-Elevator Is Built

In an elegant bit of nanoscale engineering, chemists at the University of California, Los Angeles have designed and built what must be the world's tiniest elevator, a molecular platform on three legs that can be raised or lowered on command. The device, created by Dr. J. Fraser Stoddart, a professor of organic chemistry, and colleagues, is about two and a half nanometers high. "The elevator or something like it might someday serve as a valve, opening and closing a tiny cavity to allow a few drug molecules to reach a cell." (more on earlier article)
