“…A large pore, for example, will facilitate transport to the smaller pores which act to increase the electrode area and provide additional places for electron exchange to take place. However, there have been very few examples of hierarchical porous electrodes with well-defined pores on more than one length scale reported in the literature [17,[22][23][24][25][26]. In recent work, we described the fabrication of a hierarchical template formed by coupling two different sized polystyrene latex spheres together [27].…”

“…Due to its high stability and sensitivity, nonenzymatic electrochemical technology is a good choice for glucose sensing [ 7 ]. Various nanoparticles have been reported for constructing electrochemical nonenzymatic biosensors, such as noble metal Pt nanoparticles (Pt NPs) [ 3 , 8 , 9 ], Au NPs [ 10 , 11 ], and Pd NPs [ 12 , 13 ]. However, the expensive price of these noble metals restricts their practical application.…”

A NiFe alloy nanoparticle/graphene oxide hybrid (NiFe/GO) was prepared for electrochemical glucose sensing. The as-prepared NiFe/GO hybrid was characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The results indicated that NiFe alloy nanoparticles can be successfully deposited on GO. The electrochemical glucose sensing performance of the as-prepared NiFe/GO hybrid was studied by cyclic voltammetry and amperometric measurement. Results showed that the NiFe/GO-modified glassy carbon electrode had sensitivity of 173 μA mM−1 cm−2 for glucose sensing with a linear range up to 5 mM, which is superior to that of commonly used Ni nanoparticles. Furthermore, high selectivity for glucose detection could be achieved by the NiFe/GO hybrid. All the results demonstrated that the NiFe/GO hybrid has promise for application in electrochemical glucose sensing.
