Breath sensor could offer on-the-spot cancer report

Researchers are using nanoparticles to create a material sensitive enough to analyze a person's breath in real time and detect indicators of cancer, diabetes, and other illnesses.

Scientists at Purdue University and the National Institute of Standards and Technology said today that even though diagnostic breath-analysis tools have been around for several decades, this is the first time a material has been developed that's sensitive enough to deliver on-the-spot results.
