A novel non-enzymatic electrochemical sensor based on gold nanoparticles/nicke hydroxide nanosheet (AuNPs/Ni(OH)2 NS) nanocomposite was successfully fabricated and further used for glucose sensing. The morphology and composition of AuNPs/Ni(OH)2 NS were characterized by scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction. The electrochemical properties were evaluated through cyclic voltammetry and amperometric methods. The AuNPs/Ni(OH)2 NS/GCE exhibited wide linear range (0.002–6.0 mM), a low detection limit (0.66 μM) and good reproducibility and stability. The sensor was successfully employed for glucose detection in food samples for which the sensor displayed high performance with excellent reproducibility and recovery in complex food materials.
