PVA/PEI nanofiber mats containing active GOx were produced at gold electrodes surface.
For that, a one-step, rapid and facile electrospinning process was used.
Decoration of the NFs with Au nanoparticles improved their conductive properties.
The Au NPs/GOx NFs modified electrodes were successfully used for glucose detection.
The proposed impedimetric biosensor exhibited a low limit of detection (0.9 μM).
