“…Oxide materials other than silica that have been applied to electrochemical biosensing are mesoporous Nb 2 O 5 185, 73, 199, Al 2 O 3 188, SnO 2 191, 193 and doped SnO 2 , i.e., antimony‐doped tin oxide (ATO) 75 and indium‐doped tin oxide (ITO) 192, 195, ZrO 2 194, 74, ZnO 201, TiO 2 186, 190, 191, 196, 200, MnO 2 189, 197, or Fe 3 O 4 121, 198.

“…Hydroxyapatite was also used 196, 202. These materials are prepared by the direct templating approach depicted in Figure 1, e.g., Nb 2 O 5 73, 185, ATO 75, ITO 192, ZrO 2 74, 194 or MnO 2 189, or by other routes, e.g., self‐assembly of nanoparticles generating a mesoporosity defined by the space present between NPs, e.g., TiO 2 191, SnO 2 193 or hydroxyapatite 210; the mesoporous material can be otherwise produced by electrodeposition of ZnO 201 or MnO 2 197 in the presence of a surfactant template.…”

“…Mesoporous conductive or semi‐conductive and transparent matrices constitute another attractive family of solids useful to enzyme immobilization and offering the advantage to allow the spectroelectrochemical investigation of redox proteins and the elaboration of spectroelectrochemical biosensing devices. Examples are available for transparent electrode materials such as TiO 2 186, 191, SnO 2 191, 193, ITO 192, 195, 219, or ATO 75. Figure 3 illustrates an example of such film with the schematic draw of one of them, based on cytochrome c (Cyt c) immobilized in the porous structure of a transparent and conducting ITO film (Figure 3A).…”

“…Other strategies exploit a particular way to prepare mesoporous materials, i.e., the deposition of few amount of material as thin film onto an electrode surface by controlled evaporation. First the mesoporosity can be introduced by the assembly of nanoparticles, as illustrated for TiO 2 and SnO 2 transparent mesoporous films 186, 191, 193. In this configuration, a µm‐thick mesoporous film is prepared by “doctor blade” deposition of the aqueous suspension of nanoparticles.…”

This review (239 references) is dealing with the use of mesoporous materials in the field of electrochemical enzymatic biosensors. After a brief discussion on the interest of mesoporous materials for electrochemical biosensing, a presentation of the various types of inorganic and organic‐inorganic hybrid mesostructures used to date in the elaboration of enzymatic bioelectrodes is given and the main bioelectrode configurations are described. The various biosensor applications are then summarized on the basis of a comprehensive table and some representative illustrations. The main detection schemes developed in the field are based on amperometry and mediated electrocatalysis, as well as some on spectroelectrochemistry.

Efficient Assay for the Detection of Hydrogen Peroxide by Estimating Enzyme Promiscuous Activity in the Perhydrolysis Reaction

Hydrogen peroxide is an ideal oxidant in view of its availability, atom economy, or green aspects. Furthermore, it is produced by the cell mitochondria and plays a meaningful role in controlling physiological processes, but its unregulated production leads to the destruction of organs. Due to its diverse roles, a fast and selective method for hydrogen peroxide detection is the major limitation to preventing the negative effects caused by its excess. Therefore, we aimed to develop an efficient assay for the detection of H 2 O 2 . For this purpose, we combined the enzymatic method for the detection of hydrogen peroxide with the estimation of the promiscuity of various enzymes. We estimated the activity of an enzyme in the reaction of pnitrophenyl esters with hydrogen peroxide resulting in the formation of peracid. To our knowledge, there is no example of a simple, multi-sensor demonstrating the promiscuous activity of an enzyme and detecting hydrogen peroxide in aqueous media.

Bioelectrocatalytic Reduction of Hydrogen Peroxide by Microperoxidase‐11 Immobilized on Mesoporous Antimony‐Doped Tin Oxide

The heme‐undecapeptide microperoxidase‐11 (MP‐11) was immobilized on mesoporous antimony‐doped tin oxide (ATO) thin‐film electrodes modified with the positively charged binding promotor polydiallyldimethylammonium chloride. Surface concentrations of MP‐11 of 1.5 nmol cm−2 were sufficiently high to enable spectroelectrochemical analyses. UV/Vis spectroscopy and resonance Raman spectroscopy revealed that immobilized MP‐11 adopts a six‐coordinated low‐spin conformation, as in solution in the presence of a polycation. Cathodic reduction of hydrogen peroxide at potentials close to +500 mV versus Ag/AgCl indicates that the reaction proceeds via a Compound I‐type like intermediate, analogous to natural peroxidases, and confirms mesoporous ATO as a suitable host material for adsorbing the heme‐peptide in its native state. A hydrogen peroxide sensor is proposed by using the bioelectrocatalytic properties of the MP‐11‐modified ATO.
