Abstract
A biosensor was prepared with dual cathode electrode and immobilized enzyme membrane. A nylon net was used for the immobilization of glucose oxidase and alcohol oxidase. The immobilized enzymes were placed on the surface of the electrode which was prepared with one anode and two cathodes as an oxygen electrode. The determination of components by the biosensor was based on the consumption of dissolved oxygen. The optimum condition of this system was 0.1 M potassium phosphate buffer solution, pH 7.5 at
멥쌀로 탁주를 제조하여 발효과정 중에 변화되는 에탄올 및 포도당의 함량을 동시에 측정할 수 있는 바이오센서를 dual cathode electrode를 이용하여 제작하였다. Alcohol oxidase와 glucose oxidase는 nylon net에 고정화시켜 anode가 한 개이고 cathode가 두 개인 dual cathode electrode에 부착하여 용존산소가 소모되는 변화량을 측정하여 간접적으로 포도당과 에탄올의 농도를 동시에 측정할 수 있도록 하였다. 이 시스템의 최적 조건은
