New Applications of Microelectrodes in Electroanalysis

Microelectrodes with high real surface areas and well-defined periodic nanostmctures have recently attracted much interest because of their potential applications in electrocatalysis and electroanalysis [94-96]. These electrode systems can be prepared, using templating techniques, from lyotropic liquid crystalline phases of nonionic surfactants [94,95]. In particular, the normal topology hexagonal (Hj) liquid crystalline phase has been used as a template for the synthesis of mesoporous metal thin films via the electrochemical reduction of metal salts dissolved in the aqueous domain of the liquid crystalline phases [119, 120].
