4B) revealed an obvious peak which represent clear oxidation process in the presence of glucose than its absence. The electrode with Au/GOx showed negligibly low response due to lack of GOx binding over bare Au electrode surface (not shown in figure) and current response is almost unchanged before and after the addition of glucose [36]. Altogether, the results with glucose concentration (10 mM) revealed an increase in current density than the measurements without glucose in all electrodes except Au/GOx.
