摘要：

A polythionine (PTH) functionalized ordered mesoporous carbon (OMC) material (PTH/OMC) was presented. The electrochemistry kinetic characteristics of this material are investigated and compared with pure OMC. The results showed that compared with ONIC, PTH/OMC possesses a much higher electron transfer rate. For the application of this material, an electrocatalytic based NADH biosensor was constructed on glassy carbon electrode (GCE). Instead of 0.592 V on bare GCE and 0.206 V on OMC/GCE, the amperometric detection of NADH could be effectively performed on the present biosensor with operation potential be set at 0.0 V In addition, the sensor showed good reproducibility and stability.
