“…The mesoporosity is then revealed by the removal of surfactant molecules from the film. Such oriented mesoporous silica films on electrodes have proven to be of interest for electrochemical sensing , and biosensing, ,, electrochemiluminescence, , energy, polymer nanowire growth, ,, and separation/permselective membranes. ,, Moreover, the EASA approach developed in our group is applicable to the generation of functionalized thin films in one step by self-assembly co-condensation using organosilane reagents, − including a method applicable to any kind of organofunctional groups via click chemistry for mono- or multi-functionalized materials . Such modified thin films extend the scope of application of oriented mesostructures by opening new avenues in the fields of sensing, − electrocatalysis, ,, fluorescence, and molecular electronics…”
