Article Synopsis
- Researchers are exploring the use of nanostructured metal oxide surfaces to enhance the biocompatibility and bioactivity of biodegradable iron-based materials.
- Iron oxide nanotubes were successfully synthesized on pure iron through an anodic oxidation process, creating a layer that primarily consists of α-FeO with small diameters (60-70 nm).
- In vitro studies revealed that this nanotube layer did not negatively affect cell viability or morphology, and actually improved metabolic activity in human osteosarcoma cells, indicating potential for biomedical applications like stents or implants.
Modification of the Ti15Mo alloy surface through TiO nanotube growth-an in vitro study.
J Appl Biomater Funct Mater
October 2018
In this study, ordered and uniform TiO nanotubular structures were obtained on the surface of the Ti15Mo alloy by anodic oxidation. The amorphous state of TiO nanotubes formed under different anodization conditions was investigated. Crystallization of TiO into anatase phase occurs during annealing at temperatures of around 400°C, whereas anatase to rutile transformation starts around 500°C and is completed at 800°C.
