Abstract
The conversion of insulating polymeric membrane into conducting activated carbon nanofiber (ACF) membrane and the decoration of consequent fibers with flower-like CuO/NiO nanoarchitectures are accomplished, respectively, via the carbonization and electrodeposition processes. The glucose utilization efficacy of CuO/NiO/ACF is accelerated through the diffusion and adsorption of analyte into the nanofibers' voids and stacked layers, respectively, of ACF and flower-like architectures. The conducting carbon web, binary metal oxide synergism, and porous architecture of CuO/NiO/ACF proliferate the considerable sensitivity (247 mu A mM(-1) cm(-2)), low sensing limit (146 nM), and wide linear range (0.00025-5 mM) on glucose sensing along with the real sample analysis. The concordant electrochemical glucose oxidation behavior realized at different bending angles exposes the flexibility of CuO/NiO/ACF. Thus, the free-standing, flexible, binder-less, recyclable, and cost-and time-effective features of CuO/NiO/ACF convenience the glucose detection, affording an innovative technological platform for the evolution of high performance and durable glucose sensors.
