报告内容摘要：
      Magnetic nanoparticles have the great potential in various applications including bio-medical and environmental. In our recent research, we have fabricated different magnetic nanostructures by chemical routes. We have paid a particular attention on multi-functional magnetic nanoparticles.  Water soluble superparamgnetic Fe3O4 nanoparticles have been fabricated by a single step processing.  Metal/oxide core-shell nanoparticles have shown excellent magnetic properties and chemical stability.  Pt-Au-Fe3O4 multi-functional nanoparticles have shown promising properties for bio-medical applications.  Silica nanospheres embedded with Fe3O4 with a high loading have been successfully fabricated by micro-emulsion.  More recently, we have achieved magnetic nanorings and nanotubes with a controlled geometry.  These magnetic nanorings have shown excellent performance as MRI agent.
