Polymeric ultrathin films, also called nanofilms or nanosheets, show peculiar properties making them potentially useful for several applications in biomedicine, e.g., as nanoplasters for localized drug release or as a new solution for closing endoluminal surgical wounds. In this sense, one of most challenging issues is film control in the working environment: the possibility of including magnetic components, such as magnetic nanoparticles or nanotubes, paves the way for the effective use of nanofilms in the human body, by allowing precise positioning by an external magnetic field. State of the art and new perspectives of magnetic nanofilms for biomedical applications are here presented, including fabrication, modeling, characterization and validation.
