By finely tuning the TEOS/P123 molar ratio of the octane/water/P123/TEOS quadruple emulsion system and by controlling the synthesis conditions, an ultrafine emulsion system was isolated, under the confinement of which, nanoscale silica particles with ordered large mesopores (approximately 13 nm) have been successfully constructed; the obtained mesoporous silica particles have an unusual ultrafast enzyme adsorption speed and the amount of enzyme that can be immobilized is larger than that of conventional mesoporous silica, which has potential applications in the fast separation of biomolecules.
通过精细调节辛烷/水/P123/TEOS 四重乳液体系的 TEOS/P123 摩尔比并控制合成条件，分离出一种超细乳液体系，在其限制下，成功构建了具有有序大介孔（约 13 纳米）的纳米级二氧化硅颗粒；所获得的介孔二氧化硅颗粒具有异常超快的酶吸附速度，且可固定化的酶量大于传统介孔二氧化硅，这在生物分子的快速分离方面具有潜在应用。
