According to a press release from UC Berkeley, new nanotechnology explosive detection could put bomb-sniffing dogs out of work. Berkeley researches explained they found a way to detect even "minute concentrations of explosives." The technological breakthrough resulted in small laser sensors that can be placed in a handheld device.
Comparable to picking out a blade of grass in a football field, this explosive detection nanotechnology consists of a semi-conductive layer of cadmium sulfide, magnesium fluoride and a silver sheet. Keeping nitro groups like DNT and TNT in mind, the team designed surface defects on the semi-conductor that reacts with the explosives to produce a light signal. Explosives have an electron deficiency so the stronger the deficiency, the stronger the light signal will be.
Hopefully this scientific innovation will result in shorter security lines at the airport.
