    • The exact location of immobilized GOx in the silica ball (3) is not clear, but according to references of the detailed dimensions of glucose oxidase and related reference for clear analysis of the structure of this enzyme, the longest axis of the dimeric glucose oxidase is 8.0 nm. In our experiment, the pore size of 2MA-NHS-1step and 2MA-11-NHS-1step were found to be 10.57 nm and 10.04 nm by BET experiments after the reaction of 3 with NHS-ester bound dimethallylsilane 2b and 2d, respectively. From these results, the pore diameter of the NHS-ester functionalized silica ball was thought to be enough for immobilization of the enzyme inside of the pore in silica ball (3). This speculation is supported by other references. For example, Lu et al. reported the covalent-immobilization method of enzyme by using 3- glycidoxypropyltrimethoxysilane (see Ref. [4b]). In this article, Penicillin G Acetylase (size: 7.0 nm× 5.5 nm× 5.5 nm) was immobilized the inside of silica pore (pore diameter: ca. 8 nm).

    • The Bradford method (Bio-Rad) was used for determination of the amount of immobilized enzyme according to the manufacturer's instructions. From separate experiments of Bradford analyses, the amount of immobilized GOx in 1MA-GO-1step was found to be 1.4 mg, and the amount of immobilized GOx in 2MA-GO-1step was found to be 1.9 mg. These data show the linear correlation between the loading rate of NHS-ester group and the amount of enzyme loaded.
