Electrical stimulation (ES) can accelerate bone fracture healing, but the implanted metal electrodes may cause adverse effects. Herein, the authors propose a strategy to replace the metal electrodes with a biodegradable, electrically conductive film comprising polypyrrole nanoparticles and chitosan, and functionalized with bone morphogenetic protein-2 (BMP-2). Osteoblasts cultured on this BMP-2-functionalized film and subjected to ES exhibited a twofold increase in mineralization over the control group (i.e., without immobilized BMP-2 and ES) after 21 days.
