在其表面上具有纳米孔或纳米孔的二氧化硅颗粒及其制备方法

SILICA CAPSULES HAVING NANO-HOLES OR NANO-PORES ON THEIR SURFACES AND METHOD FOR PREPARING THE SAME
摘要：
The present invention relates to silica capsules having nano-holes or nano-pores on the surface thereof, and preparation methods thereof. More specifically, relates to silica capsules having holes with a size ranging from a few nanometers (nm) to a few hundreds of nanometers (nm), on the surface thereof, multifunctional silica capsules containing magnetic nanoparticles and optical nanoparticles, and preparation methods thereof. According to the present invention, the silica capsules having holes on the surface thereof can be prepared by making an emulsion system using two fluids having different surface tensions, and selectively evaporating only one fluid of the two fluids during a process of forming a silica layer. In addition, the multifunctional silica capsules containing magnetic nanoparticles and optical nanoparticles can be prepared by loading various multifunctional nanoparticles into the two fluids.
摘要（中）：

本发明涉及在其表面具有纳米孔或纳米孔的二氧化硅胶囊及其制备方法。 更具体地，涉及具有尺寸范围从几纳米（nm）到几百纳米（nm）的孔的二氧化硅胶囊，其表面上含有磁性纳米颗粒和光学纳米颗粒的多功能硅胶胶囊及其制备方法。 根据本发明，其表面上具有孔的二氧化硅胶囊可以通过制备使用具有不同表面张力的两种流体的乳液体系，并且在形成二氧化硅层的过程中仅选择性地蒸发两种流体的一种流体来制备。 另外，含有磁性纳米粒子和光学纳米粒子的多功能二氧化硅胶囊可以通过将各种多功能纳米粒子加载到两种流体中来制备。
