Popis: Osteogenic activity is an indispensible factor that has to be considered when designing antibacterial surfaces for orthopaedic applications. To this aim, a novel DJK-5 peptide was successfully incorporated on a highly porous Ti alloy coating, through the aid of self-polymerization of dopamine. The modified surface demonstrated superior broad spectrum antibacterial efficacy against S. aureus, S. epidermidis and P. aeruginosa, respectively. Simultaneously, the incorporation of DJK-5 peptide stimulated the osteoblastic cell responses, by promoting both cell adhesion and cytoskeleton organization of MC3T3-E1 cells. Such findings would have important implication in designing implant surfaces with both antibacterial efficacy and enhanced osseo-integration potential.
