摘要

The gold nanoparticles (GNP) and functionalized carbon nanotube (f-CNT) film (GNP-f-CNT) wasprepared on glassy carbon electrode (GCE) by multiple scan cyclic voltammetry. The glucose oxidase(GOx) was physical adsorbed on the GNP-f-CNT film surface. The electrochemical measurements andsurface morphology of the as-prepared films were studied using field emission scanning electronmicroscopy (FE-SEM) and X-ray diffraction (XRD). The proposed film were demonstrated for thedetermination of dissolved oxygen using linear sweep voltammetry (LSV) and rotating disk electrodevoltammetry (RDE). The proposed electrodes for the construction of biofuel cell (BFC) was achieved-2 up to 22.6W cm , and worked well as a biosensor for both glucose and dissolved oxygen with high sensitivity of 281.86 mM cm and 205.73 L mg cm , respectively. The proposed protocolfor synthesizing the GOx/GNP-f-CNT bionanocomposite is simple, convenient and fast in operation,which is expected to find wide biosensing and bioelectronic applications.
