Abstract :
Two kinds of bioelectronic gas-sensors (bio-sniffers) with alcohol oxidase (AOD) and aldehyde dehydrogenase (ALDH) were developed for convenient analysis of ethanol and acetaldehyde in expired gas, respectively. The AOD and ALDH bio-sniffer devices were possible to monitor the concentrations of alcohol and acetaldehyde in the expired gas after drinking, and would be provide the assessment of the alcohol metabolizing level and identify ALDH-activation in the subject non-invasively.
