Nanotechnology breakthrough may allow cellphones to have breathalyzers

Cellphone breathalyzers may be on the horizon with the breakthrough by an Edmonton-based nanotechnology team.
The special sensors, called nano-optomechanical systems, are normally studied in airtight conditions. But the research of nanotechnologist Wayne Hiebert, published in the journal Science on Friday, has found the sensors work better in the open air — making them candidates for everyday use.
