Zinc and Strontium‐Doped Titania Nanotube Surfaces Enhance Antibacterial Activity and Increase Osteogenic Differentiation of Mesenchymal Stem Cells

open access: yesAdvanced NanoBiomed Research, EarlyView.
Bacterial infection and poor integration often lead to orthopedic implant failure. Modifying implant surfaces can improve osseointegration. Titanium has been engineered to form titania nanotubes doped with zinc and strontium. These surfaces were evaluated for antibacterial effects and their ability to promote osteogenic differentiation in stem cells ...
