Submission + - Nanotech 'Nose' Sniffs Out Bombs From Five Metres Away (ibtimes.co.uk)
concertina226 writes: An Israeli start-up has developed the world's first "electronic nose" that uses super-sensitive nanotechnology sensors to sniff out bombs, and can even outperform dogs.
The Tracense bomb detecting device is designed to test for numerous substances simultaneously with a high rate of accuracy, giving results almost instantly.
Odours are a combination of several specific molecules, whereby each smell contributing to the odour gives off its own specific chemical properties.
At the moment, there are systems able to break down odours using analytical chemistry equipment, but these systems are bulky and meant to be used in a laboratory, or requiring a big sample of an odour to detect what it is.
Tracense wants its invention to be an affordable portable device that can be easily used by the police and airport security, so the chip in the device contains hundreds of tiny nano sensors capable of detecting even the most minute traces of chemicals, even as low as a few molecules per 1,000 trillion.
