英文摘要	we have proposed a novel free-standing nitrogen-doped carbon nanospheres@carbon nanofibers (ncnss@cnfs) composite film with high processability for the investigation of the direct electron transfer (det) of glucose oxidase (gox) and the det-based glucose biosensing. the composites were simply prepared by controlled thermal treatment of electrospun polypyrrole nanospheres doped polyacrylonitrile nanofibers (ppynss@pan nfs). without any pretreatment, the as-prepared material can directly serve as a platform for gox immobilization. the cyclic voltammetry of immobilized gox showed a pair of well-defined redox peaks in o-2-free solution, indicating the det of gox. with the addition of glucose, the anodic peak current increased, while the cathodic peak current decreased, which demonstrated the det-based bioelectrocatalysis. the detection of glucose based on the det of gox was achieved, which displayed high sensitivity, stability and selectivity, with a low detection limit of 2 mu m and wide linear range of 12-1000 mu m. these results demonstrate that the as-obtained ncnss@cnfs can serve as an ideal platform for the construction of the thirdgeneration glucose biosensor.
