Cerium doped ZIF nanoparticles and hydroxyapatite co-deposited coating on titanium dioxide nanotubes array exhibiting biocompatibility and antibacterial property
Cerium has been used as an implanted alloy additive for many years for it can enhance the mechanical properties of the alloy and restrain the corrosion of the implant. Moreover, cerium oxide nanoparticles are often used as an antibacterial material. However, there were few researches focusing on the antibacterial properties of Ce 3+ and Ce 4+ ions, instead of their corresponding oxide, as potential antibacterial coatings. Thus in this work, we loaded Ce ions into the porous structure of the ZIF-8 nanoparticles and co-deposited them with hydroxyapatite as a composite coating onto anodized titanium dioxide nanotubes array in order to test whether it can improve the anti-corrosion and antibacterial properties of the materials without affecting the biocompatibility.
