Nickel-based metal organic framework (Ni-MOF) and carbon nanotubes composite (Ni-MOF/CNTs) is constructed via in situ self-assembly of Ni-MOF in the presence of functional CNTs solution and can be used as an efficient electrocatalytic oxidation material for glucose detection. The obtained Ni-MOF displays porous structure which is in favor of the close contact between the glucose and the active centers. Amperometric study indicates that the glucose sensor displays excellent electrochemical performance, offering a low detection limit (0.82 mu M), a high sensitivity of 13.85 mA mM(-1) cm(-2), and a wide linear range of 1 mu M-1.6 mM. Importantly, good reproducibility and repeatability, long-time stability, and excellent selectivity are obtained within the as-fabricated glucose sensor. The detection results of the real samples demonstrate the Ni-MOF/CNTs composite can be a promising candidate in glucose sensing applications. (C) 2018 Elsevier B.V. All rights reserved.
