Intracellular recording nanoscale electrode devices provide the advantages of a high spatial resolution and high sensitivity. However, the length of nanowire/nanotube‐based nanoelectrodes is currently limited to <10 μm long due to fabrication issues for high‐aspect‐ratio nanoelectrodes. The concept reported here can address the technological limitations by fabricating >100 μm long nanoscale‐tipped electrodes, which show intracellular recording capability.
