Portable breath sensor detects lifestyle diseases
The sensor claims to make it easy to identify molecules that previously could only be identified using large analysis instruments.
Focusing on the correlation thought to exist between ammonia and liver metabolism as well as well as between ammonia and Helicobacter pylori (H. pylori) infection, which is a risk factor for stomach cancer, Fujitsu Laboratories applied the ammonia-adsorbing characteristic of copper(I) bromide films to develop a sensor device that measures small amounts of ammonia in a person’s breath at a sensitivity differential that is about 2,500 times that for other gases.
In addition, by applying this technology, Fujitsu Laboratories claims to have become the first in the world to succeed in an experiment that selectively detected nonanal, which is a candidate biomarker for lung cancer.
Fujitsu Laboratories will seek to increase the types of gases the sensor can measure in order to create a sensor device that is as easy to use as a thermometer in screening for people who should undergo more detailed examinations for the early detection of lifestyle diseases.
