Technology to detect disease in human breath could be coming to your smartphone

That's the idea behind a new kind of breathalyser — one that would be much smaller and more sensitive than those used by police on the side of the road.

Noushin Nasiri, a material engineer, is trying to develop what would be the world's smallest sensor for detecting disease in a person's breath.
