Abstract
The use of meshes for large abdominal defects treatments has increased significantly since 1958, when Usher used a polypropylene mesh 1,2. Despite of the continued use, the available meshes cannot be considered ideal, since up to 8% of the cases presents organic reactions, causing physical and psychological consequences in the patients 3-5. In order to reduce the post surgery complications, nanostructured carbon and silver films or silver nanoparticles will be deposited on the polypropylene meshes by cold plasmas6-8, which modify the surface characteristics of the meshes without change their physical and mechanical properties. A biocompatible material (amorphous carbon film) will be firstly deposited on the mesh, and after silver nanoparticles will be dispersed in a controlled way, in order to add bacteriostatic and/or bactericidal properties to the meshes, reducing the incidence and/or magnitude of infectious complications.
