a New assembly method. The combination of multiple self-assembly modalities allows the fabrication of multi-layer self-assemblies with excellent functions. b New materials. The good deformation ability of new materials such as hydrogel and graphene oxide is utilized to make the stent and coating adjust to the pressure of the vessel wall, so that the stent can better fit the vessel wall. c New treatment. New drugs such as nanodrugs and miRNAs are assembled on the coating to increase cellular metabolism or release biologically active proteins through stably release into the cell. d Low cost and high security. After three-dimensional imaging of diseased blood vessels, 3D printing technology are used to create stents with appropriate shape to avoid damage to the endothelial cells of the diseased vessels.
