A research team lead by Dr. Hossam Halck at the Israel Institute of Technology have developed standard microprocessor manufacturing techniques to create sensing devices out of single walled carbon nanotubes (SWCNTs). These SWCNTs are coated with one of ten different non-polymeric, insulating organic materials. Each device reacts in a particular way when exposed to human breath containing 200 or more volatile organic chemicals.

The devices were calibrated using volunteer groups. One group comprised of non-smoking healthy individuals with no known lung cancer, the other group contained a cohort of patients with stage 4 lung cancer. The SWCNT nano-devices were able to clearly distinguish between these two groups. At this present time further trials are taking place with larger groups.

This technology would allow for fast diagnostic testing of lung cancer. This type of test might allow for lung cancer patients response to therapy to be obtained by measuring the response from the nano-device.- CT
