重点介绍了最近超亮荧光胶体介孔（纳米孔）二氧化硅颗粒的自组装。这些粒子比用量子点组装的同等尺寸的聚合物粒子亮两个数量级。与相同体积的游离染料的最大荧光相比，颗粒所显示的荧光高出三个数量级以上。我们讨论了这些粒子高亮度的本质、存在的问题、潜在的应用和前景。
Recent self-assembly of ultra-bright fluorescent colloidal mesoporous (nanoporous) silica particles is highlighted. The particles can be up to two others of magnitude brighter than polymeric particles of comparable size assembled with quantum dots. Comparing with the maximum fluorescence of free dye in the same volume, the particles can show fluorescence which is higher by more than three orders of magnitude. We discuss the nature of the high brightness of these particles, existing problems, potential applications and prospects.
