JILA and NIST Fellows David Nesbitt's and Jun Ye's recent results in their breathalyzer study have been highlighted in a new article in��Scientific American.��Using frequency combs, a particular type of laser array, scientists could detect specific molecules in the breath, including diseases like COVID-19. This research suggests huge implications for the future of disease diagnosis and prevention.��“We are training our frequency comb nose using machine learning, and once it’s trained, it becomes an electronic dog—with much greater sensitivity,” Ye says in the article.
