[57]. Research [57] has further highlighted potential complications with using
NiTi-based stents, which had the potential to induce allergic reactions or toxicity.
Functional nanocoatings containing vascular endothelial growth factor have been uti-
lized to improve endothelial cell growth on the surface of NiTi cardiovascular stents.
Specically, a nanocoating of Al

signicantly led to a 16-fold reduction in the
release rate of Ni from the stent.
Moreover, research into tissue regeneration, specically stent re-endothelializa-
tion, demonstrated the benets of nanocoatings based ...
