Titanium dioxide nanotubes (TNTs) are biomaterials with good physicochemical properties and biocompatibility. Owing to their inherent antibacterial and drug-loading ability, the antibacterial application of TNTs has received increasing attention. In this review, the process of TNT anodizing fabrication is summarized. Also, the mechanism and the influencing factors of the antibacterial property of bare TNTs are explored. Furthermore, different antibacterial strategies for carrying drugs, as well as modifications to prolong the antibacterial effect and reduce drug-related toxicity are discussed. In addition, antibacterial systems based on TNTs that can automatically respond to infection are introduced. Finally, the currently faced problems are reviewed and potential solutions are proposed. This review provides new insight on TNT fabrication and summarizes the most advanced antibacterial strategies involving TNTs for the enhancement of long-term antibacterial ability and reduction of toxicity.Keywords: antibacterial property, drug delivery, titanium dioxide nanotube, orthopedic implant, surface modificationLi YYang YLi RTang XGuo DQing YQin YDove Medical Pressarticleantibacterial propertydrug deliverytitanium dioxide nanotubeorthopedic implantsurface modificationMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 14, Pp 7217-7236 (2019)
