Glassy carbon beads are selectively functionalized on one side with an ultrathin organic layer by bipolar electrochemical reduction of diazonium salts to give Janus‐type beads with a hybrid organic–inorganic composition (see scheme). The presence of the grafted organic layers is revealed either by co‐adsorption of gold nanoparticles or by coupling with a fluorescent molecule.
