Mg alloy is of great potential in the application of vascular stent due to its degradation in physical environment and proper mechanical property.However its mechanical integrity does not meet the clinical requirement due to relatively fast degradation.Besides,in order to accelerate the reendothelialization of Mg-based stents,it needs surface modification to improve the attachment,growth and adhesion of endothelial cells(ECs).To solve the main obstacles,an anti-corrosion and quick endothelializa...
