Abstract :
Growth of a sputtered Ta2O5/ZnO/Zn0.6Mg0.4O film on a glass substrate and its application to an enzyme-modified field-effect transistor (EnFET) for glucose sensing are reported. This potentiometric glucose sensor showed a stable sensitivity to a wide range of glucose in an electrolyte solution with a detection response time constant of 3 s.
