UCSB Scientists Create Device Capable of Detecting Narcotics and Explosives

Researchers at UCSB recently created a device that can detect and differentiate between explosives, pollutants and various airborne chemicals via a microfluidic nanotechnology that mimics the mechanism behind canine chemo sensation.

The portable vapor-distinguishing “Trace Chemical Vapor Detection Cartridge” is patented by SpectraFluidics, a Santa Barbara-based company that aims to use the device to improve security, food and research industries.

Martin Moskovits, a UCSB professor of chemistry and one of the head designers of the nanotech nose, said that the invention imitates canine receptors through using silver particles in lieu of mucus membrane sensors.

“Dogs bring molecules from the environment to scent receptors in the nose and they gather these particles in their mucus membrane. The sinus is used to allure those particles to be exposed to toxins, pollutants and contaminants in the atmosphere. When enough have gathered up, a scent forms,” Moskovits said. “Many years ago we discovered a molecule that binds to silver and the silver clumps together to form little particles. At the end of the voyage a light shines on the particles and tells you what is in the air.”

They can detect Occupy protests now? Wow. what will science come up with next?
