The aim of work was to create nanocapsules for sustained and
targeted drug delivery of natural interferon alpha (IFN-α),
which is an effective medicine mainly used to treat hepatitis
viruses. The work discussed in this paper was performed as
part of the “PowTech” FP7 Marie Curie Initial Training
Network, and involved the co-encapsulation of natural
interferon alpha and superparamagnetic iron oxide (magnetite,
Fe3O4) nanoparticles (NPs).
