| 中文摘要 | a novel hybrid nanomaterial (go-mwnts) was explored based on the self-assembly of multiwall carbon nanotubes (mwnts) and graphene oxide (go). compared with pristine mwnts, such a nanocomposite could be well dispersed in aqueous solution and exhibit a negative charge. driven by the electrostatic interaction, positively charged horseradish peroxidase (hrp) could then be immobilized onto go-mwnts at the surface of a glassy carbon (gc) electrode to form a hrp/go-mwnt/gc electrode under mild conditions. tem was used to characterize the morphology of the go-mwnt nanocomposite. uv-vis and ftir spectra suggested that hrp was immobilized onto the hybrid matrix without denaturation. furthermore, the immobilized hrp showed enhanced direct electron transfer for the hrp-fe(iii)/fe(ii) redox center. based on the direct electron transfer of the immobilized hrp, the hrp/go-mwnt/gc electrode exhibited excellent electrocatalytic behavior to the reduction of h(2)o(2) and nano(2), respectively. therefore, go-mwnts could provide a novel and efficient platform for the immobilization and biosensing of redox enzymes, and thus may find wide potential applications in the fabrication of biosensors, biomedical devices, and bioelectronics. |
