Boffins build nanotube gas detector
|
Chemical engineers at MIT have used carbon nanotubes to build the most sensitive electronic detector yet for sensing deadly gases.
The technology can detect the presence of harmful gases such as sarin, mustard gas, ammonia and VX nerve agents.
It has the potential to be used as a low-cost, low-energy device that could be carried in a pocket or deployed inside a building to monitor hazardous chemicals.
