Formation of a Bacteriostatic Surface on ZrNb Alloy via Anodization in a Solution Containing Cu Nanoparticles
High strength, excellent corrosion resistance, high biocompatibility, osseointegration ability,
and low bacteria adhesion are critical properties of metal implants. Additionally, the implant surface
plays a critical role as the cell and bacteria host, and the development of a simultaneously antibacterial
and biocompatible implant is still a crucial challenge. Copper nanoparticles (CuNPs) could be a
promising alternative to silver in antibacterial surface engineering due to low cell toxicity. In our study,
we assessed the biocompatibility and antibacterial properties of a PEO (plasma electrolytic oxidation)
coating incorporated with CuNPs (Cu nanoparticles). The structural and chemical parameters of the
CuNP and PEO coating were studied with TEM/SEM (Transmission Electron Microscopy/Scanning
Electron Microscopy), EDX (Energy-Dispersive X-ray Dpectroscopy), and XRD (X-ray Diffraction)
methods. Cell toxicity and bacteria adhesion tests were used to prove the surface safety and
antibacterial properties. We can conclude that PEO on a ZrNb alloy in CaβP solution with CuNPs
formed a stable ceramic layer incorporated with Cu nanoparticles. The new surface provided better
osteoblast adhesion in all time-points compared with the nontreated metal and showed medium grade
antibacterial activities. PEO at 450 V provided better antibacterial properties that are recommended
for further investigation
