than those of 5 mM, 7 mM and 10 mM reported recently by the
electrochemical systems of neodymium hexacyanoferrate
nanoparticles glucose oxidase/chitosan modified glass carbon

electrode, respectively.30 Furthermore, our previous studies
have successfully used the NiBPE to detect sugars, trivalent

also be expected to extend successfully for electroanalysis of

In conclusion, the Ni films with a reticular morphology
supported on a conducting AuBPE substrate have been

dendrite texture Ni(OH)2/NiO(OH) film was stabilized after
a low temperature annealing treatment. This easy approach
makes possible in manufacture on a mass scale and represents

a
useful platform for electroanalysis applications. The
annealed Ni–AuBPE was demonstrated for the FIA of glucose
at an applied potential of +0.55 V vs. Ag/AgCl with excellent
sensitivity. Meanwhile, such a high surface area annealed
Ni–AuBPE can be used as an anode in a sugar–air battery
with higher energy densities.33–35 The development of portable
recycling nickel–metal hydride batteries36–38 is growing at a
record pace due to consumer demand. The research is
currently under investigation in this laboratory.
