Title: Graphene oxide–thionine–Au nanostructure composites: Preparation and applications in non-enzymatic glucose sensing
Authors: Kong, Fen-Ying, Li, Xiao-Rong, Zhao, Wei-Wei, Xu, Jing-Juan xujj@nju.edu.cn, Chen, Hong-Yuan
Source: Electrochemistry Communications. Jan2012, Vol. 14 Issue 1, p59-62. 4p.
Subjects: Graphene, Nanostructures, Glucose, Oxides, Carbon electrodes, Electrocatalysis
Abstract: Abstract: 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 0.05μmol/L.
