    摘要: The present invention relates to multi-polymer-coated magnetic nanoclusters, aqueous magnetic fluids comprising same, and methods of their use in separation procedures. The multi-polymer-coated magnetic nanoclusters comprise a super paramagnetic core, with a first polymer attached thereto, which does not render the first polymer-super paramagnetic particle complex colloidally stable, and a second polymer attached thereto, which stabilizes the complex of multi-polymer-coated magnetic nanoparticles. Methods of use comprise methods of separation, including separation of expressed protein from cells and viruses expressing the same.

    摘要: One aspect of the present invention relates to a permanently linked, rigid, magnetic chain of particles prepared by sol-gel methods. A second aspect of the present invention relates to a method of preparing a permanently linked, rigid, magnetic chain of particles comprising: coating a core material with one or more polyelectrolyte layers resulting in a coated particle; further coating the coated particle with a layer of magnetic nanoparticles resulting in a magnetic particle; coating the magnetic particle with a layer of a polycationic polyelectrolyte resulting in a coated magnetic particle; and applying a magnetic field to the coated magnetic particle in the presence of a metal oxide or metal oxide precursor capable of undergoing hydrolysis.
