JILA scientists have boosted the sensitivity of their decade-old frequency comb breathalyzer a thousandfold and can detect additional biomarkers of disease—four now, with the potential for six more. When validated and engineered into a portable design, the comb system could offer real-time, noninvasive analysis of human breath to detect and monitor diseases. JILA is jointly operated by the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder.
