Breath might be tested to measure more than sobriety if researchers at the Russell Berrie Nanotechnology Institute in Haifa, Israel, have anything to say. They've developed a sensor made from gold nanoparticles that is able to distinguish between the breath of those with lung cancer from those without.
The sensing technology, according to lead author Hossam Haick, does not require the exhalation to be pre-treated in any way; the resulting breath test is simple, affordable, and portable. (In existing tests, preconcentration of the biomarkers is required to improve detection.)
"We demonstrated that our device has a potential not … Read more
