Ni nanostructured arrays (NAs) modified by entangled carbon nanotube (CNT) networks have been fabricated via a facile chemical vapor deposition (CVD) approach and applied as an electrode for non-enzymatic glucose sensors for the first time. Compared with previously reported Ni-contained biosensors, the electrode of CNT/Ni NAs possess higher performance for the detection of glucose, showing a low detection limit (1 μM, S/N = 3), a wide linear range (0.5-10 mM) and quite high sensitivity (∼1381 μA mM<sup>-1</sup>cm <sup>-2</sup>). In addition, other excellent pr...
