| 中文摘要 | a more stably dispersing of multi-wall carbon nanotube composite (noted as pdda-mwnt), which was obtained by wrapping the mwnt with poly (diallydimethylammonium) chloride (pdda), was used for the immobilization of glucose oxidase (god) and its bioelectrochemical studies. the morphologies and structures of the pdda-mwnt composite were characterized by environment-canning electron microscopy (esem) and x-ray photoelectron spectroscopy (xps). electrochemical impedance spectroscopy (eis) and cyclic voltammetry were used to feature the god adsorbed onto the electrode modified by pdda-mwnt composite. the immobilized god at the pdda-mwnt films exhibited a pair of well-defined nearly reversible redox peaks and a fast heterogeneous electron transfer rate with the rate constant (k(s)) of 2.76 s(-1). in addition, god immobilized in this way retained its bioelectrocatalytic activity for the oxidation of glucose. the method of immobilizing god without any additional cross-linking agents presented here is easy and facile, which provides a model for other redox enzymes and proteins. |
