Boronate ester complexes generated between methylene blue (MB + )‐functionalized Au nanoparticles (NPs) and electrode surfaces are implemented to stimulate the bioelectrocatalyzed reduction of H 2 O 2 in the presence of horseradish peroxidase (HRP). Two kinds of Au NPs are prepared: Class I includes MB + /phenylboronic acid as a modifying layer, whereas Class II includes MB + /dithiothreitol as a mixed capping layer. The Class I or II NPs form boronate ester complexes with a dithiothreitol‐ or phenylboronic acid‐functionalized Au electrodes, respectively. By the cyclic loading of the NPs on the electrodes (pH 8.1), and the removal of the NPs (pH 1.5), switchable bioelectrocatalyzed reduction of H 2 O 2 is demonstrated.
