Kind: research · Impact: low

## In brief

- Researchers from the Hefei Institutes of Physical Science developed a gas sensor that detects tiny amounts of dimethyl sulfide in human breath.
- The sensor works even in the presence of interfering gases and high humidity.
- The compounds it targets are related to liver disease.

## Why it matters

A breath-based sensor for liver disease-related compounds could offer a non-invasive screening approach, though the source does not report clinical validation.
