Cerium doped ZIF nanoparticles and hydroxyapatite co‐deposited coating on titanium dioxide nanotubes array exhibiting biocompatibility and antibacterial property

Abstract

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 Ce3+ and Ce4+ 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 a…
