A one‐step grafting method of NHS‐ester group is described for the immobilization of enzymesonto a silica surface at room temperature. Pure NHS‐ester functionalized methallylsilane was prepared as a grafting reagent and showed remarkable grafting efficiency with acid catalysts at room temperature. As a result, mesoporous silica balls bearing a covalently immobilizedenzyme could be obtained with a

A surface-modified inorganic material and a preparation method thereof. A surface-modified inorganic material is provided which is obtained by allowing an organosilane compound having allyl or an allyl derivative to react with an inorganic material, particularly solid silica or ITO glass, in the presence of an acid and an organic solvent, to introduce an organic group into the inorganic material even at room temperature, as well as a preparation method thereof. The invention can effectively introduce the organic group into the inorganic material even at room temperature, and thus is very effective in introducing compounds having a thermally sensitive functional group, for example, natural compounds or proteins. It is possible to introduce various organic groups into an inorganic material and to separate and purify organic molecule-bonded organosilane compounds using a silica gel column to effectively bond them to inorganic materials.
