Detecting cancer in general is an important process to cut out the previous modes of doing so. But a new nanotechnological process for cancer detection could make diagnosis lung cancer as simple as breathing into a tube.

Researchers created a silicon gold circuit by embedding gold nanoparticles in a silicon wafer. The air blown from 40 cancer patients and 50 people with healthy lungs enabled them to track four chemicals that healthy lungs do not have: decane, trimethylbenzene, ethylbenzene, and heptanol. When the chemicals bind to the organic coat on the nanowires, they change the circuit's electrical resistance in a predictable way.

If successful with some tweaking here and there, this device could be very useful for detecting lung cancer. And very well enable early stage detection. Mad science!
