“…In turn, this could have an effect on the electron transfer rate of the SPE with Au NRs being higher compared with the SPE with Au NSs. These results are in good agreement with the report of Zhang et al (2010b) in which the authors showed that the electron transfer resistance of CuO NSs is larger than that of CuO nanowires in enzyme-free biosensors. In addition, Au NRs (1:5) showed higher current response than Au NRs (1:3).…”

“…doi:10.1016/j.bios.2011.05.012 peroxidase (HRP) with good results in terms of sensitivity and selectivity (Cai et al, 2006;Kafi et al, 2008;Won et al, 2010). However, enzyme-based biosensors have drawbacks, including a complex structure that increases cost, and poor stability because of the inherent nature of enzymes (Bai et al, 2008a,b;Lin et al, 2010;Zhang et al, 2010b). To overcome these drawbacks of enzymebased biosensors, enzyme-free biosensors have been studied by using nanoparticle (NP)-modified electrodes or direct electrodes.…”

“…In comparison to nanopowders, structured CuO films could avoid the drawbacks of complex fabrication processed, harsh modification conditions for electrodes, expensive glassy carbon electrode, and possible decline of electron transfer rate between isolated nanostructures and electrodes. Recently, CuO nanostructures (such as nanosheets [35], nanobelts [36] and nanowalls [37]) on Cu foils directly applied for glucose sensing has been explored. But, CuO thin films that were grown on other substrate such as ITO [38] and gold layer-coated glass substrate [39], have been seldom reported.…”

Novel CuO thin films composed of porous nanosheets were in situ formed on indium tin oxide (ITO) by a simple, low temperature solution method, and used as working electrodes to construct nonenzymatic glucose sensor after calcinations. Cyclic voltammetry revealed that the CuO/ITO electrode calcinated at 200 °C exhibited better electrocatalytic activity for glucose. For the amperometric glucose detection, such prepared electrode showed low operating potential of 0.35 V and high sensitivity of 2272.64 μA mM−1 cm−2. Moreover, the CuO/ITO electrode also showed good stability, reproducibility and high anti‐interference ability. Thus, it is a promising material for the development of non‐enzymatic glucose sensors.

“…It has been shown that CuO can be used in high temperature superconductors, magnetic storage media, gas sensor, field emitters and heterogeneous catalysis, and so on [4]. The CuO nanowires based sensors can take advantage of testing many objects, such as NO 2 [5], H 2 S [6], pH [7], humidity [8], glucose [9], etc.…”

To improve the efficiency of nano-electronic device fabrication, a new method named floating electrical potential assembly is proposed to realize large-scale assembly of Cu/CuO nanowires. The simulation of floating electrical potential distribution on the micro-electrode chip is performed by COMSOL software, and the simulation result shows that the coupled electrical potential on the floating drain electrodes is very close to the original electrical potential applied on the gate electrode, which means that the method can provide di-electrophoresis (DEP) force for all the electrode pairs at one time, thus realizing large-scale assembly at one time. With Cu/CuO nanowires well dispersed and micro-electrode chip fabrication, nanowires assembly experiments are performed and the experimental results show that Cu/CuO nanowires are assembled at hundreds of micro-electrodes pairs at one time, and the success rate of nanowires assembly also reaches 90%.large-scale assembly, Cu/CuO nanowires, floating potential di-electrophoresis Citation:Xu K, Tian X J, Yu H B, et al.
