Fund Project: Support of this study by the National Natural Science Foundation of China (29705001), the Chinese Education Ministry Foundation for excellent young teacher and the Natural Science Foundation of Chongqing city, are gratefully acknowledged.

Naphthol green B was used, for the first time, as a new mediator in an amperometric glucose biosensor. It is a good mediator, promoting electron transfer from glucose oxidase to graphite electrode. The biosensor shows high sensitivity to glucose at low potential with response time of 30 seconds. The linear range is from 1.5 to 18 μmol/L glucose with detection limit of 0.5 μmol/L glucose.
