Magnetically Controlled Hyaluronic Acid-Maghemite Nanocomposites with Embedded Doxorubicin.

The controllable delivery of drugs is a key task of pharmacology. For this purpose, a series of polymer composites was synthesized via the cross-linking of hyaluronate and a hyaluronate/polyacrylate mixture with FeO nanoparticles. The cross-linking imparts magnetic properties to the composites, which are more pronounced for the ternary hyaluronate/polyacrylate/γ-FeO composites compared with the binary hyaluronate/FeO composites.
