Abstract

Glucose oxidase (GOx) was immobilized between aligned carbon nanotube films (ACNTFs) using a cross-stacking method without any purification and functionalization processes. Direct electron transfer of GOx was achieved on the ACNTFs with reversible redox peaks observed at the formal potential of -0.448 V. When applied to the determination of glucose by cyclic voltammetry, the prepared enzymatic electrode exhibited a linear range from 1 to 5 mM under mediator-free physiological conditions, which makes it a promising candidate for the development of third-generation glucose biosensors.
