Publication date: Available online 17 September 2019Source: Materials LettersAuthor(s): Si Liu, Ya Zhao, Yanlian Liu, Xiaohong Yao, Peide Han, Ruiqiang Hang, Jin ZhangAbstractThe present work reports on the hydrothermal conversion of Ni-Ti-O nanopores anodically grown on NiTi alloy into nanospindles and their cytocompatibility. The results show the amorphous nanopores can transform to antase nanospindles with length concentrated at 70-110 nm and diameter at 16-24 nm upon hydrothermal treatment at 200 oC in pure water for 2 h. The nanospindles also can promote proliferation of bone marrow mesenchymal stem cells when compared with that of nanopores and bare NiTi alloy thus are promising as biomedical coatings of NiTi alloy.
