Artificial cilia spur new thinking in nanotechnology

(PhysOrg.com) -- Cilia, tiny hair-like structures that perform feats such as clearing microscopic debris from the lungs and determining the correct location of organs during development, move in mysterious ways. Their beating motions are synchronized to produce metachronal waves, similar in appearance to "the wave" created in large arenas when audience members use their hands to produce a pattern of movement around the entire stadium.
