The Cancer Breathalzyer? On Your Cellphone?

A friend forward a link to a very interesting study in the British Journal of Cancer that shows the potential for developing a breath test that can identify volatile organic compounds associated with four different kinds of cancer (breast, colon, lung, and prostate). Peng et al utilized a custom nanosensor "array of cross-reactive sensors based on organically functionalised gold nanoparticles."  It would be fascinating if this kind of array technology could be combined with the Xprize initiative to create an artificially intelligent physician on a smartphone.
