Gold nanoparticles (GNPs) were direct deposited onto the surface of indium tin oxide (ITO) electrode surface through cyclic voltammetric method. The GNPs-modified ITO electrodes were characterized by means of scanning electron microscopy (SEM), UV–vis spectroscopy and electrochemical methods. The quasi-spherical GNPs directly attached on the electrode surface with a relatively small size and a quite narrow distribution. Cyclic voltammetry and linear sweep voltammetry of glucose on the modified electrodes were performed. The GNPs-modified ITO electrodes showed high electrocatalytic reactivity towards glucose oxidation in 0.01 M NaOH and 0.05 M phosphate buffer solution (pH 7.4). The GNPs-modified transducer was successfully used for the amperometric sensing of glucose at alkaline and neutral solutions.
