- 論文の詳細を見る
The gate of ion sensitive field effect transistor (ISFET) was coated with urease-albumin membrane to fabricate a micro urea sensor. Potentiometric response of the sensor is markedly dependent on the nature of the membranes. Using the sensor with a thiner membrane (ca. 2 vim) , linear response with a slope of -44 mV/decade has been obtained over the range of 1 × 10^<-4> -5 × 10^<-3> mole/dm^3 (M) urea concentration, response time being 2 min. In contrast, for the thicker membrane (ca. 10 Vim) , Nernstian response with 30 min of the response time has been obtained. The diffusion rate of H^+ or OH^- in the membranes has been estimated to be a main factor governing the response time of the f sensor. Some operating variables such as the buffer concentration and the life time of the sensor have been also examined.
