Abstract
An amperometric sensor for uric acid and a manufacturing method thereof are disclosed, in which polyacrylamide is used to fix catalase, uricase and ferrocenecarboxylic acid on a working electrode. In determining concentration of uric acid, hydrogen peroxide is produced when enzyme and uric acid react with each other and then a reduction current generated from enzyme on the electrode with an external voltage 200 mV applied is detected. In determining concentration of uric acid, a concentration range of 2.5-20 mg/dl is achieved and sensibility of the sensor in a linear portion is 5.17 uAcm(mg/dl). In addition, reaction time required for the reaction between enzyme and uric acid is 5.17 uAcm(mg/dl).
