Graphical Abstract
Shuttle of electrons: A redox-active bisbipyridinium cyclophane stoppered by the enzyme glucose oxidase (GOx) in a rotaxane configuration on a molecular wire linked to a gold electrode (see picture) leads to the effective electrical contacting of the biocatalyst that oxidizes glucose at −0.4 V (versus saturated calomel electrode).

- 16The surface coverages cannot be directly derived from the DPVs; they were derived from a cyclic voltammogram recorded at pH 9.5 at which the FAD potential is negatively shifted (δE°/δpH≈30 mV pH−1 at pH>7) relative to the pH-independent potential of 2, to provide separate waves for both redox components in the cyclic voltammogram.

- 18The GOx-reconstituted electrode, which lacks the interlocked rotaxane-mediator and thus does not show bioelectrocatalytic oxidation of glucose, was activated in the presence of the diffusional electron-transfer mediator, ferrocene monocarboxylic acid (0.5 mM). Therefore, the reconstituted GOx exists on the surface in the biocatalytically active state.
