Exhaled Breath Ammonia Sensor
- Detailed Technology Description
- For early detection and monitoring of liver/kidney diseases
- *Abstract
-
Advances in microelectronics and new detector materials have increased the capability to detect biomarkers for various diseases. A remaining challenge is to provide sensors that are non-invasive, accurate and reliable.
Detection of ammonia during exhalation through wavelength modulation spectroscopy provides a non-invasive method to diagnose adverse health conditions such as liver or kidney diseases that are associated to ammonia fluctuation.
A sensor developed at KAUST addresses the need for accuracy by using a laser-based technology, which overcomes sensitivity and selectivity limitations that often limit gas detection in medical applications.
This technology has strong potential for the medical devices industry. Its portability, non-intrusiveness, accuracy and small cost make it very attractive for disease detection and monitoring.
