摘要：

Herein, we demonstrated a facile strategy for preparing high-loading Au nanoparticles using thionine functionalized graphene oxide as the supporting material. Glassy carbon electrodes modified with the as-obtained nanocomposites showed remarkably electrocatalytic activity towards the oxidation of glucose, leading to an enzymeless glucose sensor with a wide linear range and a lower detection limit of 0.05 mu mol/L (C) 2011 Elsevier B.V.
