“…Because only ca. 65% of this volume is pores 25 and therefore accessible to the guest, the aforementioned ratio of concentration ``inside'' and ``outside'' is 1.5610 21 M to 1.2610 24 M, or 1250. We did not thoroughly study the other derivatives of azobenzene, but they too are likely to show greatly excessive uptake.…”

“…Most probably, efforts would be pursued in designing new systems for the immobilization of biomolecules and electron transfer cofactors in order to get improved biosensors, the ceramic-carbon and screen-printed electrodes being the spearheads of such investigations. Finally, recent works on photoinduced electron transfer [307], spectroelectrochemical detectors [308], and electrochemiluminescence sensors [309] could open new scopes in combining silica-based materials with electroanalytical science.…”

This article aims to review the electroanalytical applications of chemically modified electrodes involving silica and silica-containing matrices. After a brief introduction to silica chemistry, the implication of pure and grafted silicas in electrochemistry, as well as that of the silica-based materials originating from the sol-gel technology, will be discussed. The interest of silica-modified electrodes (SiO 2 -MEs) with respect to electroanalysis will be pointed out by means of several examples. In the last five years, successful applications of SiO 2 -MEs have been achieved. Among them, silica grafted with inorganic films or organic moieties was successfully applied to the selective preconcentration or the electrocatalytic detection of various analytes. Also, the ability of the sol-gel chemistry to encapsulate enzymes within a silica matrix without preventing its activity was exploited in the development of new amperometric biosensors. These promising fields are thought to lead to significant advances in the near future, because of the explosive growth in both the synthesis of novel mesoporous organically-modified silica-based materials and the huge development of sol-gel chemistry in tailoring and construction of new modified electrodes.

“…Several strategies for synthesizing silica encapsulated biomolecules have been reported. The bulk of these were based upon alkoxide-based sol-gel processing [4][5][6][7][8][9]. Typically, a silicon alkoxide, for example tetraethylorthosilicate (TEOS) or tetramethylorthosilicate (TMOS) is hydrolyzed and condensed around the biomolecule, usually introduced within a pH buffered solution.…”
