A new type of composite particle is developed. It is consisted of a magnetic particle and several liposome particles and has a structure as shown in Fig. 1. Bi-molecular layered lipid-membrane liposome particles that can contain some pharmaceutical molecules in inner compartments are located around a magnetic particle, i.e., a silica-coated hematite through the binding properties of protein molecules. Because of its magnetic properties, we can control its location and hence will be able to supply pharmacy locally.

Schematic representation of magneto-liposome.
Each region of the drawing shows a hematite particle (gray), a silica layer (light blue), a protein layer (yellow), or several liposome particles (green) from the center of the composite |
