摘要: We describe a method for the production of nanoelectrodes at apex atomic force microscopy (AFM) probes. The are formed from single-walled carbon nanotube AFM tips which act as template formation nanowire through sputter coating with metal. Subsequent deposition conformal insulating coating, and cutting probe end, yields disk-shaped nanoelectrode tip whose diameter is defined by amount metal deposited. demonstrate that these probes capable high-resolution combined electrochemical topographical imaging. flexibility this approach will allow fabrication controllable size composition, enabling study activity nanoscale.
