主　　题：orange juice extended-gate field effect transistor SnO2/ITO glass vitamin C sensor 

摘      要：An extended-gate field effect transistor (EGFET)of SnO_2/ITO glass was applied to manufacture the vitamin C ***,we immobilized the ascorbate oxidase with 3-glycidoxypropyltrimethoxysilane (GPTS)method to measure the different concentrations of the vitamin C solution in an optimum measurement *** order to find the best measurement conditions of the biosensor,we studied the vitamin C sensor in different pH values of the phosphate buffer solution (PBS).Additionally,we used experimental results to discuss the response time and response voltage to compare vitamin C with orange juice for the vitamin C sensor.
