Submitted Abstract

The engineering of surfaces presenting innovative features such as improved hygiene, easy-to-clean, anti-soiling, anti-dust, etc., awakens more and more the interest of the industry and the consumers.Besides, the strategies of manufacturing and the consumption habits evolve in a context characterized by a growing willingness from all the participants for a better protection of the environment, ecosystems, aswell as of the health and safety of individuals.The BioADBD project aims at conferring to metallic and polymer surfaces, universal antimicrobial coatings resistant to ageing and fouling, by covalently attaching biocidal biomolecules to surfaces. Torapidly transfer the results to industry, flexible processes with low cost investments, easily transferable to production lines and giving the opportunity to promote green products have been chosen. Theantimicrobial surfaces are elaborated from an atmospheric plasma technique to deposit functional thin films followed by attachment of peptide in aqueous solution. To obtain optimal antimicrobial properties,the biomolecules are carefully selected and then, they are synthesized and activated in order to be covalently attached to the plasma interlayer with a specific orientation without loss of the 3D structure.The effect of the antimicrobial surface chemistry and structure on the antimicrobial properties and durability is studied by standard testing at laboratory and industrial scale.
