Detecting lung cancer could soon be as trivial as determining alcohol intoxication levels. A breath analyzer made out of functionalized gold nanoparticles may make lung cancer diagnosis noninvasive and portable.The good news is that it appears to work in a fairly basic manner. Initial testing was don on people found to be fairly well along with the disease.
The authors neglect to mention if they will try to figure out how sensitive their sensors are to different stages of lung cancer. All of the cancer subjects in this study had primary stage-3 or stage-4 lung cancer, so the disease had already progressed significantly. It would be important to know if their sensors are useful in stages 1 and 2 of the disease, as being able to diagnose patients in earlier stages would vastly improve their chances of survival.There is speculation that some other diseases might be detectable with this too.
Thanks to the Devils Kitchen for the pointer. Kitchen's over there, the workshop's over here.
