Abstract
백금작업전극과 광가교화된 효소고정화막을 가진 ISFET 포도당 및 자당센서가 제조되었다. 효소반응의 부산물인 과산화수소수( H 2 O 2 )는 백금전극표면에서 분해되어 센서의 감지특성을 개선시키고, 광가교화 고분자(PVA-SbQ)가 효소고정화막으로 이용되어 센서의 응답시간을 단축하였다. 그리고 백금전극의 면적변화에 따라 센서의 응답크기는 증가하였다. 센서의 응답시간은 3∼5 분이었으며, 30∼300mg/dl 의 포도당 및 자당농도에서 센서의 선형적인 응답을 보였다. The ISFET glucose and sucrose sensors containing platinum electrode and photopolymeric enzyme membrane were fabricated. The platinum working electrode was used for the electrolysis of hydrogen peroxide, which was the other product of the enzyme reaction, to improve sensing characteristics of the sensors. In order to improve response time, photo-crosslinkable polymer(PVA-SbQ) was used to the matrix for the enzyme immobilized membrane. The characteristics of glucose and sucrose sensors were investigated according to the variation of platinum electrode area. The response time was about 3∼5 minutes and determinations of glucose and sucrose in the range of about 30∼300mg/dl could be possible.
