A research team leaded by Elisabete Castanheira and Paulo Coutinho, of the Centre of Physics of University of Minho, has been focused on the development of magnetic liposomes (“magnetoliposomes”), which combine magnetic nanoparticles and liposomes. The developed systems have been tested as nanocarriers for new potential antitumor drugs. The latter have been obtained at the Centre of Chemistry of University of Minho (Maria João Queiroz’s research group). In this study, recently published, a new molecule especially active against breast cancer was tested.
