Plastic nanowires sense gasses
Cornell University researchers have devised a simple way to position conducting polymer nanowires on an electrode, and have made a prototype high-speed chemical detector that is capable of sensing minuscule amounts of ammonia gas. The researchers are working on other polymer materials that are able to detect other gasses. The method could ultimately be used to make a device that has an array of wires sensitive to different chemicals.
