• found to be equal to 27 s−1. It appears that the heterogeneous electron transfer rate for the adsorbed BOx does not depend on electrode nanostructuring. These results are in excellent agreement with our previously published data concerning the influence of gold nanoparticles on enzymatic bio

• -electrocatalysis [24]. kcatapp values for BOx/Au and BOx/NIL/Au electrodes were found to be 30 and 39 s−1, respectively (Supporting Information File 1, Table S1), whereas kcat in homogeneous catalysis was measured to be 57 s−1 (see above). kcatapp values for BOx/Au and BOx/NIL/Au electrodes were recorded at 30 and
