摘要：

The phenoxazine compound Meldola Blue (MB) is shown to efficiently mediate the electron transfer from reduced glucose oxidase to a conventional carbon paste electrode. The mediation process is exploited for developing an amperometric biosensor for glucose, which yields a linear response to 0-25 mM glucose at an operating potential of 50 mV (vs. SCE), where interfering reactions do not occur. Experimental variables such as enzyme loading or operating potential are explored. A stable response is observed over several months.
