Abstract
We used a mid-infrared frequency comb to detect SARS-CoV-2 infection by measuring exhaled breath molecular contents. A trial study was conducted for the first time and excellent diagnostic power was found. Mid-infrared laser sensing technologies can have unprecedented potential for non-invasive optical diagnoses of some of the most pressing medical cases.
