Biocompatibility, corrosion resistance and antibacterial activity of TiO2/CuO coating on titanium

Microstructure, Wettability, Corrosion Resistance and Antibacterial Property of Cu-MTa2O5 Multilayer Composite Coatings with Different Cu Incorporation Contents

“…The peak located at 951.8 eV could be ascribed to the Cu 2p 1/2 from Cu or Cu 2 O in the high-resolution spectrum of Figure 8e, while the peak located at 953.7 eV is from CuO. In addition, two satellite peaks are also observed, which are attributed to CuO (Figure 8c), which further confirms the existence of CuO in the coating [33]. Since copper is easy to be oxidized, the oxidation state of copper is observed in this Cu doped in C3 coating.…”

Electrochemically Obtained TiO2/CuxOy Nanotube Arrays Presenting a Photocatalytic Response in Processes of Pollutants Degradation and Bacteria Inactivation in Aqueous Phase

“…This is the reason why it has been more intensively studied among other catalysts nowadays. Cu and TiO 2 combinations were studied in different modifications including photodeposition of copper [25], microwave co-precipitation technique [26], layer films [27], alloy rods [28], nanocrystals [19], composite coating on wooden substrate [29], copper decorated TiO 2 nanorods [30], combination of magnetron sputtering and annealing treatment [31], doped nanoparticles [32] or radiolytic deposition of copper species at the surface of TiO 2 nanotubes [33]. However, properties of nanostructures containing copper obtained via anodic oxidation using alloys are still rather unknown, and very little research has been undertaken to understand the quantity influence of copper in the Cu-TiO 2 nanostructured composite regarding the photocatalytic activities of Cu-doped TiO 2 .…”

Characterization, Bioactivity and Antibacterial Properties of Copper-Based TiO2 Bioceramic Coatings Fabricated on Titanium

“…These results suggested that Cu-based MAO coatings on cp-Ti could be a promising candidate for biomedical dental implant applications.TiO 2 -based coatings have been suggested to improve corrosion resistance, bioactivity and biocompatibility of implant surfaces. They have recently received great attention for the biomedical applications owing to their more stable chemical composition [11,12]. TiO 2 were fabricated on cp-Ti by various surface coating methods including sol-gel [13], anodic oxidation [14], magnetron sputtering [15], electrophoretic deposition [16], acid etching [17,18], laser surface treatment [19], plasma spraying [20,21] and micro arc oxidation [22][23][24][25] etc.…”

“…Furthermore, it actively takes part in various enzyme-based processes, for bone metabolism stimulates new vessel formation and accelerates early skin wound healing [46,47]. Therefore, it is beneficial for bone tissue formation [12]. Moreover, copper exhibits excellent antibacterial properties versus a broad spectrum of bacteria, including gram-positive and gram-negative bacteria by interfering DNA replication and disrupting cell membranes [48][49][50].In particular, there have been some promising studies on the fabrication of antibacterial Cu/CuO-nanoparticles containing Cu-incorporated TiO 2 coatings on cp-Ti by using the MAO technique for the last five years [42,45,[51][52][53][54][55][56].…”
