Preparation of multi-functionalized Fe3O4/Au nanoparticles for medical purposes

- The preparation of magnetite/gold nanoparticles is described.
- A polyelectrolyte multilayer is adsorbed on the magnetic core prior to gold coating.
- The polyelectrolyte multilayer formation improves the stability of the coating.
- The magnetite/gold nanoparticles are able to load DOX and/or BEV.
- The DOX and BEV can be simultaneously released from the particles.
