Sol-Gel Approach for Development of the Mesoporous Structures for Creation of the Sensors and Disposal of Low Molecular Weight Toxic Substances from Environmental Objects

摘要

Mesoporous sol-gel materials are among the ideal host matrixes for immobilizing enzymes because of their large pore volumes and controllable pore sizes appropriate for inclusion compounds. Although indirect enzyme immobilization in mesoporous materials has been achieved by impregnating of the MCM41 matrix with an enzyme, there are only few reports on one-step direct immobilization of bioactive species in surfactant-templated mesoporous sol-gel materials. We demonstrate here the principle by immobilization of 2,4D herbicide and mycotoxins T2 as model system. With that goal in view, various silica matrices with miscellaneous structural parameters were prepared and characterized.
