The Cover Feature illustrates the nanocomposite material FeOcPc−Ni/GO made of stacked graphene oxide sheets covered with carboxylated iron phthalocyanine molecules connected through ultra‐small nickel hydroxide nanoparticles, providing a very effective electrocatalyst for glucose sensing based on its oxidation to gluconic acid in aqueous media. Reproducible, high signal‐to‐noise ratio responses were achieved at potentials as low as +0.5 V (at the right side), realizing a sensitive and robust amperometric non‐enzymatic glucose sensor as a consequence of synergic effects, as evaluated by batch injection analysis (BIA).
