Breath analysis systems
Breath-markers for disease diagnosis
<Breath-markers associated with specific diseases>
- In exhaled breath, there are lots of volatile organic compound gases closely related to diseases.
- For instance, acetone with a sweet smell is detected in the mouth-exhaled breath of diabetes, and
ammonia gas with a fishy smell is found in the breath of liver and kidney dysfunction patients.
Such gases are called breath-markers.
- Detecting breath-markers, we can diagnose disease without time-wasting blood/urine tests,
expensive image takings, and dangerous examinations such as biopsy.
- Performed with portable gas sensors, routine screening of diseases and even their early detection
could be possible.
Hand-held breath analyzers
<Hand-held breath analyzers for detecting various diseases>
- Breath-marker selective gas sensors are integrated into a breath sampling tube with several
complementary systems.
- With the hand-held analyzer, we can monitor metabolic activities in our body and several diseases.
- Our laboratory focuses on the development of fat bun monitoring breath analyzers and helicobacter
pylori infection detection sensors.
Miniaturization
<Miniaturization of current breath analyzers into a chip>
- Our laboratory aims at reducing the size of the current setting into a chip-scale for their integration in
smartphones and other small electronic devices.
- For this, we are designing breath samplers, sensor arrays, and other systems, as well as sensing materials.
