The cover picture shows a sub‐monolayer of ssDNA‐stabilised reduced graphene oxide assembled by electrostatic adsorption. The reduced graphene sheets are capable of mediating electron transfer from redox species in solution to electrode surfaces modified by an insulating self‐assembled monolayer. This behaviour contrasts with the insulating properties of the graphene oxide precursor. Voltammetric and impedance responses provide information on density of state and electrochemical reactivity of these carbon‐based nanostructures. Details can be found in the article by D. J. Fermín et al. on p. 2956 ff.
