TL;DR: Bioactive polymers bearing sulfonate and carboxylate groups were grafted onto Ti6Al4V alloy surfaces by a two-step procedure to assess the influence of the grafted polymers on cell response and found the NaSS grafted surfaces showed the highest degree of cell adhesion while the MA-Na SS grafted surface showed the lowest degree ofcell adhesion.

On the mechanisms of biocompatibility.
TL;DR: It is shown that, in the vast majority of circumstances, the sole requirement for biocompatibility in a medical device intended for long-term contact with the tissues of the human body is that the material shall do no harm to those tissues, achieved through chemical and biological inertness.
