ZnO nanowires may lead to better chemical sensors, high-speed electronics

Devices for detecting dangerous substances can literally be life savers, in situations ranging from soldiers on the battlefield to luggage screeners at airports. Yet chemical sensors now available for such tasks have their drawbacks. They aren’t always sensitive enough to detect tiny amounts of a hazardous chemical, for instance. Once exposed it can takes hours until they are ready to sense again.
