• a variety of polymers. The carbonization of electrospun polyacrylonitrile nanofibers can be employed to fabricate CNFs [24]. Lin et al. reported that an electrospun-CNF-modified carbon-paste electrode (CNF–CPE) could be used for the mediatorless detection of NADH [25]. Electrodes modified with Pd

• spectrophotometer (UNNICO Instruments Co., Ltd., Shanghai) was used to calculate the activity of laccase. Preparation of ECNFs The ECNFs were prepared by the following steps. Firstly, the electrospinning solution was prepared by dissolving 10 wt % polyacrylonitrile (PAN) powders in DMF with magnetic stirring for 8
