本發(fā)明屬于材料制備領(lǐng)域，特別涉及一種高載硒量的介孔二氧化硅長效納米材料的制備方法。背景技術(shù)：硒作為人體必需的微量元素之一，是人體多種酶的組成成分。一直以來，它在、拮抗重金屬、增強(qiáng)人體免疫功能等方面發(fā)揮著重要作用。有研究顯示硒納米顆粒與乙酰膽堿氯化物和槲皮素復(fù)合對超級細(xì)菌具有高和活性，并且不會產(chǎn)生耐藥性。另外，有研究發(fā)現(xiàn)羥基磷灰石上的納米硒涂層對銅綠假單胞菌和金黃色葡萄球菌具有良好的性。從生物安全性的角度考慮，硒元素的內(nèi)源性與或外源性生長因子的高成本、復(fù)雜的制造和非預(yù)期的副作用相比，具有更加可靠的安全性和經(jīng)濟(jì)性。但是硒的營養(yǎng)活性劑量與其毒性劑量之間范圍較窄，過量會導(dǎo)致硒中毒。納米硒的發(fā)明不僅保留了傳統(tǒng)硒的優(yōu)點，并能有效改善這一難題。然而，納米硒極易發(fā)生團(tuán)聚，嚴(yán)重影響其生物活性和生物利用度。因此，構(gòu)建適當(dāng)?shù)募{米硒可調(diào)節(jié)釋放體系，可以降低其副作用和提高其生物學(xué)活性。介孔二氧化硅(msns)因其粒子尺寸均一可調(diào)、可調(diào)節(jié)的介孔結(jié)構(gòu)、載藥效率高、生物相容性好和易功能化及表面修飾等優(yōu)勢，被用于構(gòu)建速釋、緩釋和控釋系統(tǒng)等方面。</p><div
