摘要：
An electrochemlcally generated tetrathlafulvalene redox mediator provides a convenient and reversible indicator reagent for a glucose fiber-optic sensor. The fabrication and characterization of this sensor based on a thin-layer cell configuration are described. The performance of the fiber-optic sensor is compared with that of an amperometric enzyme electrode In flow-injection and steady-state analyses. The upper limit of the linear range In the flow-Injection mode is about 12 mM, whereas in the steady-state mode It Is about 3 mM. The sensor Is less prone to Interfering species and dissolved oxygen. It can be used continuously for 2 days without significant loss of activity. © 1990, American Chemical Society. All rights reserved.
