Abstract:
The present disclosure relates to a polymer-iron oxide composite nanoparticle, a polymer-iron oxide composite nanoparticle including a silica coating layer coated on the surface of the polymer-iron oxide composite nanoparticle, a DNA-containing polymer-iron oxide composite nanostructure including DNA attached on the silica coating layer, a method of preparing the same and a method of controlling expression of a gene.

Claim (Index 6):
A method of preparing a polymer-iron oxide composite nanostructure, the method comprising:\n mixing a polymer and an iron oxide nanoparticle in an organic solvent, adding an aqueous solution of polyvinyl alcohol (PVA), stirring the same, and evaporating the organic solvent to obtain a polymer-iron oxide composite nanostructure; and coating the surface of the polymer-iron oxide composite nanostructure with silica.
