text: Nanoelectrodes are tiny electrodes made of metals or semiconducting materials having typical dimensions of 1-100 nm.
  Various forms of nanoelectrodes have been developed taking advantage of the different possible fabrication techniques: among the most studied are the nanoband, disk, hemispherical, nanopore geometries as well as the different forms of carbon nanostructures.
  It is necessary to characterize each produced electrode: size and shape determine its behavior. The most used characterization techniques are:
  *  Electron microscopy
  *  Steady-state voltammetry
  *  Atomic force microscopy (AFM) 
  *  scanning electrochemical microscopy (SECM)
  There are mainly two properties that distinguish nanoelectrodes from electrodes: smaller RC constant and faster mass transfer. The former allows measurements to be made in high-resistance solutions because they offer less resistance, the latter, due to radial diffusion, allows much faster voltammetry responses. Due to these and other properties, nanoelectrodes are used in various applications:
  *  Studying the kinetics of fast reactions
  *  Electrochemical reactions
  *  Studying small volumes, such as cells or single molecules
  *  As probes for obtaining high-resolution images with scanning electrochemical microscopy (SECM)
