Abstract
An ethanol-sensing bio sensor was developed using catalase reaction. The method consists of supplying alcohol and given concentration of hydrogen peroxide, which reacts competitively with catalase. The resulting amount of oxygen from this reaction is analysed using a dissolved oxygen(DO) electrode. The sensor can be also used for alcohols other than ethanol. In the developed sensor, the measurable concentration range was about 18 mM of ethanal and the response time was within 30-90 seconds. The proposed sensing system is simpler and better in sensing performance compared to the systems using alcohol oxidase or alcohol dehydrogenase where NAD(H) has to be supplied. 16 refs., 2 tabs., 5 figs.
