摘要：

This paper describes the voltammetric behavior of a TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl) modified electrode prepared by the electrochemical polymerization of nitroxyl radical precursor containing phenol side chain in aqueous solution. The prepared TEMPO-modified electrode exhibits a symmetrical reversible redox wave at +0.6 V versus Ag/AgCl, which originates from the electron transfer between the phenol-polymerized layer and the electrode. Using the TEMPO-modified electrode, the anodic peak current for glucose was enhanced in a concentration-dependent fashion, showing that glucose was oxidized by the electrocatalytic effect of TEMPO. A high linear response to the glucose concentration ranging from 0.1 to 20 mmol L-1 was obtained.
