A New Way to Make Ultrasensitive Explosives Detectors (article)

The future of explosives detection lies in the form of nanoparticle research. Hewitt-Packard and University of California at Irving researchers have found a new way to make nanoparticle arrays that could lead to the development of extremely precise chemical sensors able to detect liquid explosives. This technique will make it easier and less expensive to produce the nanoparticles and thus more practical to incorporate this technology into security procedure. While a few more years are needed before this breakthrough will result in new scanning devices, it is reflective of a growing field of research in this volatile time period.
