Magnetic nanoparticles have been assembled into the bilayer membrane of block copolymer vesicles. The nanoparticles decorate the hydrophobic/hydrophilic interface, which leads to bridging of adjacent bilayers and the formation of oligo-lamellar vesicles. The nanoparticle uptake of the vesicles is sufficiently high to become magnetophoretic in external magnetic fields as shown by video microscopy.
磁性纳米颗粒已被组装到嵌段共聚物囊泡的双层膜中。这些纳米颗粒修饰疏水/亲水界面，导致相邻双层膜桥接并形成多层囊泡。如视频显微镜所示，囊泡对纳米颗粒的摄取量足够高，以至于在外部磁场中具有磁泳现象。
