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...
An alcohol oxidase (AOD) immobilized gas-sensor (bio-sniffer) with stick-type configuration was developed for convenient analysis of ethanol vapor. The stick-type sniffer device was constructed in a sandwich configuration with a filter paper placed between carbon- and Ag/AgCl electrodes. The electrode-coated paper was shaped by knife into 2 mm-wide stick. In order to isolate a sensitive- (length:...
