Current Work

Microbial infection of medical devices is one of the main causes of their failure, triggered by the microbial adhesion and biofilm formation on their surface. Biofilms are characterized by communities of microorganisms strongly attached to each other and to a biomaterial surface, embedded in an exopolymeric matrix. One important property of the biofilm matrix is the resistance to antibiotics. In this way, the development of new multifunctional antimicrobial coatings is an emergent need. This work reports the development of different coatings produced by sputtering; DLC, ZrCN, TiCN and TiN, all doped with silver to confer antibacterial activity.
