Review—Recent Advancements in the Utilization of Indium Tin Oxide (ITO) in Electroanalysis without Surface Modification

Indium tin oxide (ITO), as an electrode, has superiority over metal electrodes commonly used for electroanalysis due to its low cost, low electrochemical background response, wide working potential window, easy surface functionalization and commercial availability. However, researchers have often modified its surface with electron mediators/electrocatalysts to improve its electrocatalytic properties. The modification of the ITO surface with...
