Fabrication of a test pattern with interdigitated gold electrodes (channel length 12 mu m) on a biodegradable substrate is achieved by direct laser ablation of a Au film using a high-precision multifunction infrared-laser scan marker. The whole process involves two solvent-free steps: Au film deposition by sublimation followed by maskless ablation. The approach is suited for fast prototyping of a variety of materials. We demonstrate the fabrication of a water-gated organic field effect transistor on the biodegradable poly(lactic-co-glycolic acid) scaffold and its operations in water. (C) 2013 AIP Publishing LLC.
