| Outline of Final Research Achievements |
An ethanol sensing and imaging system in the gas phase has been developed for analysis of breath ethanol. This breath gas imaging system has been expected to be easy, rapid and painless approach for sampling from patients to diagnose diseases. The system provides the image of ethanol distribution as chemiluminescence (CL) on the enzyme-immobilized mesh. The spatio and temporal changes in CL generated by ethanol in exhaled breath after ethanol oral administration was detected by employing an electron multiplier CCD camera. Breath samples from volunteers with aldehyde hydrogenase 2 (ALDH2) (+) and (-) are detected and analyzed with the imaging system. This imaging system for the human odor and skin gas has been expected to be the safe and useful assessment for metabolism in the body.
