首次证明了发光半导体纳米粒子和磁性氧化物纳米粒子同时封装在聚合物微胶囊中。高发光CdTe半导体纳米晶体作为发光标记，而磁性Fe3O4纳米粒子允许通过磁场对胶囊进行外部操作。所介绍的方法是通用的，足以允许以类似的方式制造不同类型的多功能胶囊。本文介绍了多功能水相容胶囊在生物系统中的控释和定向给药。
The simultaneous encapsulation of both luminescent semiconductor and magnetic oxide nanoparticles in polymer microcapsules is demonstrated for the first time. Highly luminescent CdTe semiconductor nanocrystals serve as luminescent markers, while magnetic Fe3O4 nanoparticles allow external manipulation of the capsules by magnetic field. The method introduced is general enough to allow the fabrication of different types of multifunctional capsules in a similar way. The use of multifunctional water-compatible capsules introduced in this paper for the controlled release and directed drug delivery in biological systems is envisaged.
