Single-Walled Carbon Nanotubes as Templates and Interconnects for Nanoelectrodes

A bottom‐up approach for metal nanoelectrode fabrication is described involving the electrodeposition of a noble‐metal nanoparticle at the exposed end of a single‐walled carbon nanotube (see figure). The nanotube end serves as a template for nanoparticle electrodeposition, while the tube itself interfaces the deposited nanoparticle with macroscopic leads. The fabrication method is general and can easily be adapted to generate single‐particle electrodes or arrays.
