Self-assembled nanosheets on NiTi alloy facilitate endothelial cell function and manipulate macrophage immune response

Stenting has been widely adopted for the treatment of cardiovascular diseases, but the complications such as in-stent restenosis and late stent thrombosis cannot be completely avoided, which are closely related to endothelial dysfunction and inflammatory response. In the present work, oxide nanosheets were grown on the surface of nearly equiatomic NiTi alloy by alkaline corrosion (AC), aiming at yielding favorable endothelial functionality and...
