“…The bonding mechanism between the coating and the substrate is complicated, and the bonding strength can be affected by many factors, such as the surface state of the substrate, preparation parameters, substrate temperature, intermediate layer, coating thickness, post-heat treatment [1,4,29,70], etc. For a multilayer Cu-MTa 2 O 5 coating, its adhesion strength is higher than that of the single layer Ta 2 O 5 coating due to the introduction of the multiple intermediate layers of Ta 2 O 5 -TiO 2 /TiO 2 /Ti.…”

“…Ti6Al4V titanium alloy, as a medical implant material, has been commonly applied in dentistry, orthopedics, and other fields due to its excellent corrosion resistance, mechanical properties, and biocompatibility [1,2,3,4]. However, clinical studies have indicated that Ti6Al4V titanium alloy-related implants would be corroded by body fluids, releasing toxic and side-effectmetal ionssuch as V 5+ and Al 3+ [5,6], and causing local immune dysfunction [7], inflammation, and cytotoxic reactions in the human body [8].…”

For the enhancement of the anticorrosion and antibacterial performance of the biomedical alloy Ti6Al4V, a novel Cu incorporated multilayer Ta2O5ceramic composite coating Cu-Ta2O5/Ta2O5/Ta2O5-TiO2/TiO2/Ti (coating codeCu-MTa2O5) was developed by radio frequency (RF) and direct current (DC) reactive magnetron sputtering. Meanwhile, to better display the multilayer Ta2O5 coating mentioned above, a monolayer Ta2O5 ceramic coating was deposited onto the surface of Ti6Al4V alloy as a reference. The surface morphology, microstructure, phase constituents, and elemental states of the coating were evaluated by atomic force microscopy, scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy, respectively. The adhesion strength, wettability, anticorrosion and antibacterial properties of the coating were examined by a scratch tester, contact angle measurement, electrochemical workstations, and plate counting method, respectively. The results showed that the deposited coatings were amorphous and hydrophobic. Cu doped into the Ta2O5 coating existed as CuO and Cu2O. A Ta2O5-TiO2/TiO2/Ti multi-interlayer massively enhanced the adhesion strength of the coating, which was 2.9 times stronger than that of the monolayer Ta2O5coating. The multilayer Cu-MTa2O5 coating revealed a higher corrosion potential and smaller corrosion current density as compared to the uncoated Ti6Al4V, indicating the better anticorrosion performance of Ti6Al4V. Moreover, a 99.8% antibacterial effect of Cu-MTa2O5 coated against Staphylococcus aureuswas obtained.

Rapid transmission of infectious microorganisms such as viruses and bacteria through person-to-person contact has contributed significantly to global health issues. The high survivability of these microorganisms on the material surface enumerates their transmissibility to the susceptible patient. The antimicrobial coating has emerged as one of the most interesting technologies to prevent growth and subsequently kill disease-causing microorganisms. It offers an effective solution a non-invasive, low-cost, easy-in-use, side-effect-free, and environmentally friendly method to prevent nosocomial infection. Among antimicrobial coating, zinc oxide (ZnO) stands as one of the excellent materials owing to zero toxicity, high biocompatibility to human organs, good stability, high abundancy, affordability, and high photocatalytic performance to kill various infectious pathogens. Therefore, this review provides the latest research progress on advanced applications of ZnO nanostructure-based antibacterial coatings for medical devices, biomedical applications, and health care facilities. Finally, future challenges and clinical practices of ZnO-based antibacterial coating are addressed.

“…On the surface of Ti6Al4V, Ding et al successfully prepared a ZnO-doped tantalum oxide multilayer composite coating (ZnO-Ta x O y ) by magnetron sputtering which showed that the ZnO-Ta x O y coating has great potential in improving the corrosion resistance and antimicrobial performance of Ti6Al4V implants. However, the cytocompatibility and optimal design of ZnO-Ta x O y coatings (e.g., composition, coating thickness, preparation parameters) need to be further improved [ 67 ].…”

“…In a study, a ZnO-doped tantalum oxide (Ta x O y ) multilayer composite coating was deposited by magnetron sputtering at room temperature. The potentiodynamic polarization curves revealed that ZnO-doped multilayer composite coating had higher corrosion potential and lower corrosion current density (1.12 ± 0.004 µA/cm 2 ) than that of Ta x O y coating, showing better corrosion inhibition [ 67 ]. Roknian et al indicated that the corrosion current density had a 93% reduction for the sample containing ZnO nanoparticles at a concentration of 15 g/L in comparison with the uncoated Ti substrate [ 58 ].…”

Titanium (Ti) implants are widely used in dentistry and orthopedics owing to their excellent corrosion resistance, biocompatibility, and mechanical properties, which have gained increasing attention from the viewpoints of fundamental research and practical applications. Also, numerous studies have been carried out to fine-tune the micro/nanostructures of Ti and/or incorporate chemical elements to improve overall implant performance. Zinc oxide nanoparticles (nano-ZnO) are well-known for their good antibacterial properties and low cytotoxicity along with their ability to synergize with a variety of substances, which have received increasingly widespread attention as biomodification materials for implants. In this review, we summarize recent research progress on nano-ZnO modified Ti-implants. Their preparation methods of nano-ZnO modified Ti-implants are introduced, followed by a further presentation of the antibacterial, osteogenic, and anti-corrosion properties of these implants. Finally, challenges and future opportunities for nano-ZnO modified Ti-implants are proposed. Graphical Abstract
