An overview is presented dealing with the use of pure, chemically modified, and sol‐gel‐derived silicates for designing electrode materials that are then exploited in various electroanalytical applications. The exploration of the potential consequences of such inorganic solids when used in electrochemical environments has intensified since 1995. This review focuses on recent advances achieved with silica‐modified electrodes (SiO 2 ‐MEs) in the fields of electroanalysis. After a description of the attractive properties of silica‐based materials for the electrochemical community, an outline of the preparation methods for SiO 2 ‐MEs is given, and their relevance to various areas of electroanalysis is discussed.
