Vertically aligned carbon nanofiber (CNF) arrays, particularly when coated with a polypyrrole film, show well‐defined electrical properties with extremely low impedance. The polymer film also serves as a biomaterial (with great freedom of chemical and biological modification) for cell/tissue engineering to create an intimate subcellular electrical–neural interface, which is desirable for implantable biomedical devices. The Figure shows a single PC12 neural cell (green) spanning collagen‐coated CNF microbundles.
