Lasers for analyzing our breath?
February 28th, 2008

According to the Optical Society of America (OSA), U.S. researchers have shown it is possible to use lasers to analyze our breath to detect diseases such as asthma or cancer. This technique — hold your breath — is called ‘cavity-enhanced direct optical frequency comb spectroscopy.’ It is based on research done in the 1990s and which led to the 2005 Nobel Prize in Physics. The researchers add that ‘while the efficacy of this technique has yet to be evaluated in clinical trials, monitoring the breath for such biomarkers is an attractive approach to medicine because breath analysis is the ultimate non-invasive and low-cost procedure.’ I’m not sure that I would like a laser blasting in my mouth, but read more…
