アルデヒド化合物ガス用バイオセンサの研究 Gas-phase biosensor for aldehyde chemicals
Most of aldehyde chemicals such as acetaldehyde, formaldehyde, etc. are defined as Specified Malodor Chemical Substances by the Environment Agency in Japan. In this research, a gas-phase biosensor for aldehyde chemicals was constructed by incorporating an aldehyde dehydrogenase (ALDH) immobilized electrode into a flow reaction cell. The sensor was used to measure acetaldehyde (0.525-20ppm) and formaldehyde (50-2000ppb) in the gas-phase with high selectivity for aldehyde vapor in the presence of other gas-phase chemicals and gave a negligible response to these chemicals.
