| 英文摘要 | A supramolecular recognition functionalized electrode (beta cd-nanoau/fc-ito) which exhibits redox-activity was prepared through supramolecular assembly of beta-cyclodextrin (beta cd) capped gold nanoparticles (beta cd-nanoau) on the ito previously coated with a monolayer of ferrocene residues (fc-ito). the immobilization of beta cd-nanoau on fc-ito was confirmed by atomic force microscopy (afm), and the supramolecular nature of the immobilization approach was also confirmed by cyclic voltammetry. on the other hand, the electrocatalytic activity of beta cd-nanoau/fc-ito electrode was also studied. ne electrocatalytic activity toward ascorbic acid (aa) was enhanced compared with that at the fc-ito electrode, and a linear relationship existed between the anodic peak and the concentration of aa in the range of 5.3 x 10(-5) to 3.0 x 10(-3) m with a detection limit (s/n= 3) of 4.1 x 10(-6) m. |
