Self-assembly of magnetic surfactants has developed rapidly in physical chemistry, materials science and biomedicine science. By incorporating paramagnetic component within the cation or anion, magnetic surfactants exhibit a strong magnetic response and enhanced hydrophobicity. By subtle design, magnetic surfactants could self-assemble to generate various magnetic aggregates, biomaterials and nano-materials, such as the bacillus-shaped bilayer vesicle, thermotropic liquid crystals, DNA hybrid nanosphere as well as magnetic fullerene, graphene, mesoporous silica and Au nanoparticles. This review highlights the properties of magnetic surfactants as well as their self-assembly behavior and applications.

磁性表面活性剂的自组装在物理化学，材料科学和生物医学科学中发展迅速。通过将顺磁性组分掺入阳离子或阴离子中，磁性表面活性剂表现出强大的磁响应和增强的疏水性。通过精巧的设计，磁性表面活性剂可以自组装产生各种磁性聚集体，生物材料和纳米材料，例如杆菌形双层囊泡，热致液晶，DNA杂化纳米球以及富勒烯，石墨烯，介孔二氧化硅和金纳米粒子。这篇综述重点介绍了磁性表面活性剂的性质及其自组装行为和应用。
