Quantification of glucose is critical in healthcare applications. Herein, in order to take advantage of both catalytic activity of NiO for glucose oxidation and high conductivity of CNTs, NiO films with different thicknesses were deposited on the surface of stacked-cup carbon nano tube (SCCNT) using atomic layer deposition (ALD) technique. Using the NiO/SCCNT composites, we demonstrated the fabrication of an electrochemical sensor with high sensitivity of 1252.3 μA cm−2 mM−1 and an ultrafast response (<2 s) for glucose determination in alkaline solution (0.1 M KOH). Additionally, exploiting ALD technique provided us with an opportunity to deposit NiO on the SCCNT surface with different thicknesses, which in turn, enabled us to evaluate thoroughly the effect of different thicknesses of NiO on glucose measurement.
