Researchers are developing a new laser system for fast, non-invasive, onsite breath analysis that may be used to screen people for a range of diseases including diabetes, infections and various cancers.
The instrument is being equated to an "optical dog's nose" which uses a special laser to measure the molecular content of a sample of gas.
"Rather than sniffing out a variety of smells as a dog would, the laser system uses light to "sense" the range of molecules that are present in the sample," said Dr James Anstie, from the University of Adelaide's Institute for Photonics and Advanced Sensing (IPAS).
