New gas sensor detects liver disease–related compounds in breath

Researchers have recently developed a gas sensor that can detect tiny amounts of dimethyl sulfide in human breath, even in the presence of interfering gases and high humidity. The study was carried out by researchers from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with the Key Laboratory of Odor Pollution Control of the Ministry of Ecology and Environment and Shenzhen Technology University.
