In an upcoming issue of Nano Letters -- a technical journal of the
American Chemical Society -- HP researchers, working in partnership with
researchers at the University of California at Irvine, describe a new process
for manufacturing nanoparticle-based ultrasensitive chemical sensors that have
the potential for detecting a single molecule of an explosive or other hazardous
chemical.
The detection system, which can be built using existing
semiconductor manufacturing methods, suggests that the sensors could be employed on battlefields and even in airports -- where they might be able to detect the minutest presence of a variety of liquid explosives.
That sort of thing will really come in handy for Israelis trying to keep suicide bombers out of certain areas. They can have the detector at a check point and might even catch militants who are merely handling the chemicals to make bombs. Whatever the case that business could be quite a blockbuster that HPQ could get into on the ground floor.
