A vertically aligned carbon nanofiber (VACNF) based amperometric glucose sensor

摘要

Due of the clinical significance of measuring blood glucose levels of diabetic patients substantial research and development efforts have been devoted to the realization of reliable glucose sensors for in vitro or in vivo applications [1]. Wang et al introduced a mediator-free and membrane-free biosensor which provided a novel direction for biosensor development [2]. On the other hand the presence of defect sites in vertically aligned carbon nanofiber (VACNF) results in better mechanical stability, sensitivity and response compared to carbon nanotubes (CNT) for sensor applications [3–4]. Based on these scientific observations a mediator-free, bienzyme, glucose sensor incorporating VACNF is proposed in this paper.
