This communication describes the use of xurography as a new technique for the rapid fabrication of gold disk electrodes with highly reproducible areas. Adhesive vinyl films and a cutting plotter were used to produce masks containing the electrode layouts, and recordable compact disks (CDs) were used as gold source. Electrode area was defined by transferring the vinyl adhesive mask to the gold surface. The electrochemical behavior of the vinyl-CDtrodes was studied by cyclic and square wave voltammetry experiments on model systems such as potassium ferrocyanide, sulfuric acid, and dopamine. The electrodes constructed using this technique meets the most important characteristics of a disposable device: low cost, reproducibility between different devices, and possibility of large-scale production.
