| 中文摘要 | supramolecular organized multilayers were constructed by multiwalled carbon nanotubes modified with ferrocene-derivatized poly(allylamine) redox polymer and glucose oxidase by electrostatic self-assembly. from the analysis of voltammetric signals and fluorescence results, a linear increment of the coverage of enzyme per bilayer was estimated, which demonstrated that the multilayer is constructed in a spatially ordered manner. the cyclic voltammograms obtained from the indium tin oxide (ito) electrodes coated by the (fc-pah@cnt/gox)(n) multilayers revealed that bioelectrocatalytic response is directly correlated to the number of deposited bilayers; that is, the sensitivity is tunable by controlling the number of bilayers associated with ito electrodes. the incorporation of redox-polymer-functionalized carbon nanotubes (cnt) into enzyme films resulted in a 6-10-fold increase in the glucose electrocatalytic current; the bimolecular rate constant of fadh(2) oxidation (wiring efficiency) was increased up to 12-fold. impedance spectroscopy data have yielded the electron diffusion coefficient (d-e) of this nanostructure to be over 10(-8) cm(2) s(-1), which is typically higher than those systems without cnt by at least a factor of 10, indicating that electron transport in the new supramolecular architecture was enhanced by communication of the redox active site of enzyme, redox polymer, and cnt. |
