水溶性量子点（QD）已经通过经由反相微乳液封装在二氧化硅内来制备（参见图）。的量子点显示可比的量子产率的ZnS封端的CdSe，但比有机涂层的水溶性量子点毒性小得多。该方法可用于量子点应用，例如生物标记和光稳定发光器件。
Water-soluble quantum dots (QDs) have been prepared by encapsulation within silica via a reverse microemulsion (see Figure). The QDs display comparable quantum yields to ZnS-capped CdSe, but are much less toxic than organic-coated water-soluble QDs. This method could be used for QD applications such as in biological labeling and in photostable light-emitting devices.
