Sensitive equipment such as dog nose

The new bio-based design of odor receptors in dogs is capable of rapidly detecting hazardous chemicals.

Scientists at the University of California, Santa Barbara, in the United States, predict that in the near future, ultra-sensitive devices capable of 'smelling' explosives or harmful chemicals will be commonplace in public places. Same as the type of smoke detector.

Teams led by expert Carl Meinhart and Martin Moskovits have designed a device that uses nanotechnology to mimic the biological mechanisms of odor receptors in dogs.

'We have made a device with a sensitivity equivalent to or more than a dog's nose , ' ' Gizmag said in a statement from Meinhart.

According to the press release, liquid-filled micro-channels will absorb and concentrate molecules, then amplify their spectral signals under the laser. After that, the connected computer began analyzing the information obtained, comparing it with the stored data warehouse and thus drawing conclusions about the type of chemical.

"The device is capable of instantly detecting and identifying each type of chemical in a fraction of a billion or less," said another member, Brian Piorek.
