AbstractMarine biofouling caused a serious loss for submerged artificial substrates, surface modification with antifouling agents is one of the commonly used methods to control biofouling. In this study, we reported an effective approach to control marine biofouling on stainless steel surface based on interactions between a derived antimicrobial peptide (M2-DA) and stainless steel surface. M2-DA was synthesized by conjugation of magainin II and dopamine, which was subsequently used for modifying the surface of stainless steel. XPS, AFM and contact angle analysis indicated that M2-DA bound on substrate surface successfully, meanwhile, morphology and wettability changed remarkably after modification. The thickness and robustness of MA-DA on substrate were also measured. The results of V. natriegens and C. farmeri adhesion assays demonstrated that M2-DA treated surfaces possess an excellent antibacterial performance, and the amount of adhered bacteria decreased 99.79% and 99.33%, respectively. The strategy may provide a useful reference for marine antifouling and some other relevant fields.
