| 中文摘要 | multiwall carbon nanotubes (cnts)-modified electrode has been prepared by using ionic liquid (il) as the binder. the as-prepared cnts-il composite modified electrode has good biocompatibility and is a suitable matrix to immobilize biomolecules. glucose oxidase (gox), containing flavin adenine dinucleotide as active site, stably adsorbed on modified electrode surface has resulted in the direct electron transfer. the electron transfer rate of 9.08 s(-1) obtained is much higher than that of gox adsorbed on the cnts papers (1.7 s(-1)), and the process is more reversible with small redox peak separation of 23 mv this may be due to the synergetic promotion of cnts and il to electron transfer of the protein, especially the il as the binder, showing better electrochemical properties than that of chitosan and nafion. furthermore, gox adsorbed at the modified electrode exhibits good stability and keeps good electrocatalytic activity to glucose with broad linear range up to 20 mm. besides, the simple preparation procedure and easy renewability make the system a basis to investigate the electron transfer kinetics and biocatalytic performance of gox and provide a promising platform for the development of biosensors. |
