“…The antimicrobial activity of Cu-TiO2 coatings was improved due to the inhibitory effect of Cu. Meanwhile, the osteoblastic adhesion, spreading, early proliferation and late differentiation on Likewise, a unique structure with a micro-/nano-morphology can also be obtained in Cu(NO 3 ) 2 electrolyte due to field-assisted chemical etching of NO 3 − . Huang et al [62] believed that the use of Cu(NO 3 ) 2 instead of AgNO 3 as the electrolyte may avoid the potential cytotoxicity of heavy metal ions.…”

Ti and its alloys are the most commonly-used materials for biomedical applications. However, bacterial infection after implant placement is still one of the significant rising complications. Therefore, the application of the antimicrobial agents into implant surfaces to prevent implant-associated infection has attracted much attention. Scientific papers have shown that inorganic antibacterial metal elements (e.g., Ag, Cu, Zn) can be introduced into implant surfaces with the addition of metal nanoparticles or metallic compounds into an electrolyte via micro-arc oxidation (MAO) technology. In this review, the effects of the composition and concentration of electrolyte and process parameters (e.g., voltage, current density, oxidation time) on the morphological characteristics (e.g., surface morphology, bonding strength), antibacterial ability and biocompatibility of MAO antimicrobial coatings are discussed in detail. Anti-infection and osseointegration can be simultaneously accomplished with the selection of the proper antibacterial elements and operating parameters. Besides, MAO assisted by magnetron sputtering (MS) to endow Ti-based implant materials with superior antibacterial ability and biocompatibility is also discussed. Finally, the development trend of MAO technology in the future is forecasted.

“…A biomaterial is a nonviable matter used in a medical device intended to interact with biological systems [1]. Due to minimal tissue reactions, titanium and its alloys have been widely used in various biomedical applications, such as artificial joints, bone surgery and implant industries [2,3]. The attribution oxide layer, which is naturally formed on the surface of the considered metals, yields a favorable biological response [4].…”

“…Biomedical titanium (Ti) and its alloys have been widely used in blood vessels, artificial joints, dental implantations and bone screws [1][2][3] on account of their excellent mechanical properties, good corrosion resistance and favorable biocompatibility. However, implant-associated infection (IAI) remains one of the most devastating postoperative complications [4,5] despite strict sterilization and systemic antibiotic prophylaxis prior to surgery.…”
