英文摘要：

Janus particles have asymmetry dual-faced structure, attributing to their particular properties, their potential application fields are numerous, such as emulsion stabilization, photonics, biosensors, drug delivery, and electronics. The recent progress on the synthesis of Janus particles is reviewed. Five general routes for the synthesis of Janus particles, i.e. microfluidic shaping, toposelective surface modification, template-directed self-assembly, controlled phase separation and controlled surface nucleation are discussed in detail. Existing problems for each fabrication technique are also concerned. In the view of low cost and high yield, the routes based on controlled phase separation and controlled surface nucleation will be probably developed more widely.
