Mouse urine creating "artificial nose" special protein effect peculiar (map)

Keywords: mouse urine "artificial nose" special protein

According to the United Kingdom "nature" magazine website reported that recently scientists find little mouse urine has special characteristics, scientists are using the mouse urine to the artificial nose and hyper-sensitivity of smell detection equipment, the use of mouse urine of special devices and equipment can smell trace explosives or pollutants, or identify a different scent.

According to reports, from the University of Pei, Professor-led a study group: in mouse urine contains a special kind of urinary protein MUPS, this protein can slow the odor molecular absorption and release, to help the mouse nose easily distinguish smell. The experts will be mouse urine in this particular protein MUPS extracted smudge in the artificial nose device uses quartz-crystal.

Then use the current stimulate micro-Crystal quartz, and thus its vibration frequency changes combined with artificial nose devices distinguish smell. According to experts, in the use of mouse urine in this particular protein MUPS, artificial nose and hyper-sensitivity of smell detection equipment for precision will reach 1,000,000th, can detect a billion minutes of smell volatiles (text data), shows a very exaggerated flourishes.

According to experts, is currently on the market of artificial nose and sense of smell detection device sensitivity are not very high, generally using polymer. Use quartz device micro-Crystal is not common, but use mouse urine is the first time. At the same time, the Pere research team led by Professor of the pig's nose and a dog's nose, even they also study the tentacles of grasshoppers, hope from these animals find more valuable things to improve these artificial nose and equipment stability and sensitivity.

Currently, Pere Professor has the mouse urine contains special protein research achievements into is located in Germany's international organization for chemical and smell (isocs) made a presentation, scientists said that the use of this protein in artificial nose and the device has a high market value, in the future will generate considerable economic benefits. At present, scientists have received EU funding, began marketing operation.
