Studies on carbon nanotubes (CNT) become a hot topic in the world due to the unique one-dimensional tubular structure and subtle physical and chemical properties of CNT. Compared with other area, the application of CNT in analytical chemistry has been studied recently. In the present dissertation, using CNT as interfacial material, the functionalized CNT electrodes were constructed; the electrocatalysis and separation of CNT-modified electrodes and its recognition ability after incorporating cyclodextrins (...
