Enzyme catalytic membrane based on a hybrid mesoporous membrane

摘要

Immobilization of glucose oxidase (GOD) within a hybrid mesoporous membrane with 12 nm pore diameter was successfully achieved, resulting in catalytically high efficiency during flow of a glucose solution across the membrane. Enzyme encapsulation within a porous inorganic host has provoked significant interest because it can render enzymes more mechanically robust and thermally stable as well as more easily separable from the reaction media. Mesoporous silica materials have been considered as a suitable host due to their inherent characteristics of high surface area and pore volume, tunable pore size accommodating dimensions of enzymes, and mechanical stability.
