초록

Urea-Sensor was fabricated by immobilizing urease on ISFET's gate using BSA(bovine serum albumin) and glutaraldehyde, and its characteristics were examined. This sensor showed approximately linear characteristic in the urea concentration range of $3{\times}10^{-5}-10^{-9}$ (g/ml). Fast response time was obtained and minute amounts of expensive enzyme were used in comparison to general electrode type biosensors.
