The exploration of noble metal-free nanoarrays as high-activity catalytic electrodes for glucose biosensing holds great significance. Herein, we propose a Ni nanoparticle-decorated TiO 2 nanoribbon array on a titanium plate (Ni@TiO 2 /TP) as an effective non-enzymatic glucose biosensing electrode. The as-prepared Ni@TiO 2 /TP electrode demonstrates rapid glucose response, a wide linear response range (1 μM to 1 mM), a low detection limit (0.08 μM, S/N = 3), and high sensitivity (10 060 and 3940 μA mM -1 cm -2 ), with good mechanical flexibility and stability. Moreover, it proves efficient in glucose biosensing in real human blood serum and cell culture fluid. Thus, it is highly promising for practical applications.
