Triple Modification of Alginate Hydrogels by Fibrin Blending, Iron Nanoparticle Embedding, and Serum Protein‐Coating Synergistically Promotes Strong Endothelialization

Stent therapy can reduce both morbidity and mortality of chronic coronary stenosis and acute myocardial infarction. However, delayed re‐endothelialization, endothelial dysfunction, and chronic inflammation are still unsolved problems. Alginate hydrogels can be used as a coating for stent surfaces; however, complete and fast endothelialization cannot be achieved. In this study, alginate hydrogels are modified by fibrin blending, iron nanoparticle...
