Sulfonate groups grafted on Ti6Al4V favor MC3T3-E1 cell performance in serum free medium conditions

Ten years ago, we synthesized “bioactive model polymers” bearing sulfonate groups and proposed a mechanism of their modulation effect at different steps of the cell response. Then, we set up the grafting of polymers bearing sulfonate on Ti6Al4V surfaces by a grafting “from” technique making sure of the creation of covalent bonds between the grafted polymer and the Ti6Al4V surface. We have checked and confirmed the positive effect of grafted...
