Sniffing Out Cancer
Makarand writes "Researchers at the Univeristy of Rome are developing an
electronic nose that
can sniff out cancer by sampling people's breath. The instrument uses sensors
that respond to the presence of chemical compounds in the patient's breath.
For example, lung cancer patients exhale alkanes and benzene derivatives
which the electronic nose will try to detect. The sensors are quartz crystal
sensors coated with a substance that binds to a range of organic chemicals.
If certain molecules in the breath bind to this surface coating they change
the natural vibration frequency of the crystal."
"can sniff out cancer by sampling people's breath."
;-)
Yeah, it is called cigarette smoke, and we've known it is a carcinogen for 40 years now. I do have trouble identifying which stench is the benzyne, and which is the nicotine though
Saskboy's blog is good. 9 out of 10 dentists agree.
would they sample to check for colon cancer?
