AB - Due to their excellent mechanical properties and biodegradability, biodegradable magnesium alloy vascular stents have become a hot topic in current research on vascular stent material. However, the further application of magnesium alloy is limited by its rapid degradation rate and insufficient ability to promote surface endothelialization. This study proposed a strategy of co-depositing a PDA-LYS coating on the surface of magnesium alloy treated with an alkaline pre-heating process. Experimental results demonstrated that the PDA-LYS composite coating significantly improved the corrosion resistance of the magnesium alloy. Furthermore, with the increase in LYS content in the samples, the coating facilitated the adhesion and proliferation of endothelial cells and effectively inhibited the excessive proliferation of pathological smooth muscle cells. In summary, the PDA-LYS composite coating had a positive impact on the biocompatibility of magnesium alloy, which has offered a new approach for surface modification of magnesium alloy vascular materials.Graphical abstract[graphic not available: see fulltext]
