G9d@vd This contribution highlights some recent advances in the synthesis of monodispersed colloidal spheres loaded with superparamagnetic components for external manipulation. We firstly discuss how Fe3O4 nanoparticles can be directly coated with silica to form core–shell particles using a sol–gel approach. We then focus on the demonstration of new materials for such an application, with Pb and amorphous Se as the typical examples of metals and semiconductors, respectively. We also illustrate how colloidal spheres of amorphous Se can be converted into Ag2Se and then MSe (M = Zn2+, Cd2+, and Pb2+) without changing the spherical shape. Combined together, these synthetic methods could enable the synthesis of monodispersed colloidal spheres with controlled size, smooth surface, and superparamagnetic features for fabricating photonic crystals whose band structures can be configured using an external magnetic field.

楼主真是厉害，想必楼主的文献阅读很大量阿，呵呵！！！

呵呵，夏幼南的，这篇文章见过，不过都是一些很老的了，好像他已经写过n篇类似的综述了，而且内容大同小异！
