| Abstract: | Layer-by-layer (LbL) assembled core-shell particles are currently studied immensely due to their advantages of tailored dimensions and compositions. They have potential technological applications in areas such as medical/biochemical diagnostics and drug delivery. In this paper, the fabrication of magnetic composite core-shell particles and hollow spheres based on LbL self-assembly and colloidal templating by direct removal of core materials using a variety of chemical and physical methods are mainly reviewed. Some specific examples on the exploitation of core-shell particles in drug delivery, bioassay and biolabeling applications are given. |
