Detecting diseases from your breath?

Quote
We report on an artificially intelligent nanoarray based on molecularly modified gold nanoparticles and a random network of single-walled carbon nanotubes for noninvasive diagnosis and classification of a number of diseases from exhaled breath. The performance of this artificially intelligent nanoarray was clinically assessed on breath samples collected from 1404 subjects having one of 17 different disease conditions included in the study or having no evidence of any disease (healthy controls). Blind experiments showed that 86% accuracy could be achieved with the artificially intelligent nanoarray, allowing both detection and discrimination between the different disease conditions examined....

I know nothing of nanoarrays, but don't consider this idea impossible. There's stiff sniff competition, though. Dogs sometimes outperform million dollar equipment on specifics. Diabetes sniffers sense when their owner is dangerously high in blood sugar. Much more convenient that having the patient understand when breathing into some device might be required.

Other dogs warn for oncoming epileptic seizures. I don't know if that is from smell or owner's behaviour. Successful cancer detection has also been reported. Just hit me - are there dogs who specialize in detecting environmental pollution of different kinds?

Wasps are even better at sniffing, and easily trained, and cheap.

So of course they won't be used.

They can be trained to check water for sewage leaks/human fecal contamination. I'm not sure what else has been done with pollution but you can probably train them to sniff out most things.

NAZIs?
Are we there yet?
