This is a really neat concept. I have a MD and a background in biochemistry, and can say most people I've met in the field of oncology don't nearly have the creativeness and audacity of this kid's idea. Essentially he's using the carbon nanotube materials, sending an electric current through it, and detecting minute voltage changes that occur when cancer proteins bind to the antibodies laced over the nanotubes. The cost of using nanotubes to detect cancer, however, may be quite prohibitive. Think 500-1000 dollars per test. On a population screening level, I don't think most governments or insurance companies would go for it.
