中文摘要	Self-assembled magnetic vesicles based on cationic double-chain dimethyldioctadecylammonium(DODMA+) encapsulating two kinds of magnetic polyoxometalates, K10[Co4(H2O)2(PW9O34)2] 20H2O({Co4P2W18}) and MoVI72FeIII30O252L102 180H2O with L ¼ H2O=CH3COO =Mo2On 8=9 ({Mo72Fe30}), were fabri-cated in mixed-solvent solution (CHCl3 +CH3OH, 4:1 v/v). The vesicles were characterized by scanningelectron microscopy (SEM), transition electron microscopy (TEM), atomic force microscopy (AFM), anddynamic light scattering (DLS). SEM and TEM images show that three-dimensional hollow shells of themagnetic vesicles can survive after solvent evaporation. The room-temperature magnetic properties weremeasured, indicating that {Co4P2W18} and {Mo72Fe30} retain their magnetic properties after embedding inthe vesicles. Interestingly, the self-assembled magnetic vesicles can be aligned under an external mag-netic ﬁeld, which make them ideal candidates as magnetic biosensors for drug-releasing materials.
