The ultrathin films are able to be injected using minimally-invasive syringe needles and can be used as a platform to deliver molecular and cellular drugs. The use of shape-memory polymer also enables unprecedented temperature-dependent control to allow for adhesion and removal of the nanosheets on biological surfaces.
Concept of syringe-injectable, self-expandable and ultra-conformable magnetic ultrathin films (MNP-SMP nanosheets) composed of polyurethane-based shape-memory polymer and magnetic nanoparticles.
Syringe-injectable biomaterials, medical devices and engineered tissues have attracted great attention as minimally-invasive implants for diagnosis, therapy and regenerative medicine. Free-standing polymeric ultrathin films, commonly referred to as polymeric nanosheets, are one of the commonly used platforms for syringe-injectable biomedical devices because of their flexibility and conformability.
