Magnetic nanosheet adhesion to mucosal tissue

Polymeric single layer nanosheets have been recently developed and proposed as drug-delivery systems. By spin coating deposition, the nanometric thickness can be easily controlled, and plenty of polymers can be deposed, thus obtaining biocompatible and resistant sheets. For all these reasons, the possibility to use them as drug carriers or "nanoplasters" for closing incisions (both externally and internally the human body) has been envisaged. One of most challenging issues is the handling and the positioning of these films within the working environment, controlling the movement of the film, possibly by using non invasive tools: the possibility to include magnetic components, such as magnetic nanoparticles or nanotubes, will pave the way for the effective use of nanosheets in the human body, by allowing precise positioning by an external magnetic field.
