Nanoparticles and nanowires for better explosive detectors

Researchers at Hewlett-Packard and the University of California at Irvine say they have a process that uses basic semiconductor manufacturing to fabricate arrays of nanoparticles in minutes. Ultrasensitive chemical sensors based on nanoparticles have the potential to detect a single molecule of an explosive or other hazardous chemical.
