The classical field of electroanalysis is emerging as a new and exciting tool in
the 21st century. The characterisation, detection and theoretical behaviour of
ions and electrons at the nanoscale is a growth area, of immense interest in the
diverse fields of science and technology ranging from biological applications,
fuel cells, surface and materials characterisation to sensing. Electrochemistry
at the nanoscale is closely linked to interfacial chemistry at the solid-liquid,
liquid-liquid phases, material sciences and condensed matter physics. The
paradigm shift in electrochemistry started in the 1980s with development of new
trends such as structured micro and nano-electrodes allowing atomic scale and
dynamic investigations. Enabling in-situ techniques such
