\nThe two main challenges to faced when implanting a prosthesis lie in good tissue integration while preventing infection<\/strong>. In collaboration with chemical experts from the CNRS UMR 7244 unit, CERAVER developed and then industrialized a surface treatment process allowing a control of a cell response and an inhibition of bacterial adhesion under experimental conditions. Indeed, the radical grafting of a bioactive polymer, poly(sodium styrene sulfonate) onto prosthesis surface demonstrates continuously its excellent in vitro and in vivo results<\/strong> [1-5], opening the way to a new generation of bioactive prosthesis in several application fields<\/strong>.<\/p>\n

The objective of the \u201cACTISURF\u201d project is to offer a new generation of bioactive orthopedic prostheses. The goal is to promote bone regeneration around the prosthesis, while inhibiting bacterial adhesion<\/strong>. This technology is patented in Europe, the USA and Japan. Protein mediation allows control of the host response, thereby avoiding the creation of bacterial biofilm. This high value-added coating is currently under clinical investigation in France for orthopedic applications. Developments are underway in fields such as traumatology, dentistry, neurosurgery, cardio-vascular\u2026and so on.<\/p>\n
