%X A novel NiO-decorated flexible buckypaper (NiO-BP) was fabricated by a simple and scalable vacuum filtration method for electrochemical detection of glucose. The NiO-BP consists of two layers: one side is composed of purified single-walled carbon nanotubes, serving as the supporting layer, whereas the other side comprises NiO-loaded single-walled carbon nanotubes, serving as the catalyst layer. The morphology and structure of NiO-BP were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction and Raman spectroscopy. The fabricated NiO-BP was applied to the electrochemical detection of glucose. Under optimized conditions, the sensor exhibited a wide linear range of 0.1¨C9 mM for the determination of glucose with high sensitivity (2701 ¦ÌA mM¨C1 cm¨C2) and a short response time (<2.5 s). The present work reveals that the buckypaper with a unique double-layer structure is promising for wearable biosensors
