Abstract

Silicon nanowires develop a uniform synthetic bone coating under an electric-field bias in simulated body fluid. The hydroxyapatite-coated nanowires (see Figure) support fibroblast attachment and proliferation, and remain responsive to electrical bias even after coating, providing a system for electric-field modulated tissue regeneration.
