摘要：

In this study, the new nanocomposites of beta-cyclodextrin (beta-CD) and multi-walled carbon nanotubes (MWNTs) have been prepared and deposited on the indium tin oxide (ITO) electrodes to form the beta-CD/MWNTs modified ITO electrodes. These novel modified electrodes exhibited the abilities to lower the electrooxidation potentials of NADH substantially (ca. 600 mV) in comparison with bare ITO electrodes. Furthermore, a linear response to NADH in the concentration range of 4.0 x 10(-6) to 3.2 x 10(-3) mol/L was observed, with a detection limit of 8.0 x 10(-7) mol/L. Such ability of the novel nanocomposites to promote the electron-transfer reaction of NADH suggests great promise for dehydrogenase-based amperometric biosensors.
