Sensor detects asthma, cancer, diabetes in breath

KAIST professor Il-doo Kim 김일두 has developed a sensor that can diagnose diseases by measuring the concentration change of the specific gases in the breath, with out blood or imaging tests. Animal protein is used as a catalyst.  The researchers claim that detection can be done at the time of disease metabolism, enabling early diagnosis.

Hydrogen, acetone, toluene, ammonia, hydrogen sulfide, nitrogen monoxide, and moisture are biomarker gases are emitted at high concentrations in patients with  diseases such as asthma, lung cancer, and Type 1 diabetes.  The 16 sensor array system recognizes human fingerprints and individual breathing patterns associated  with each condition.

Technion professor Hossam Haick has been studying non-invasive breath-based detection of disease, including cancer, since 2007, and his Na-Nose technology was commercialized in 2013.
