“…87 As displayed in Figure 9g, the two spin-orbital components exhibited at 347.38 and 351.18 eV corresponded to the Ca 2p spectrum. 53 In Figure 9h, the two diffraction peaks at 885.78 and 900.98 eV can be attributed to the Ce 3d5/2 and 3d3/2 with the Ce 3+ oxidation state, respectively. On the other hand, the observed peaks at 899.38 and 916.88 eV related to CeO 2 , which indicated the presence of the Ce 4+ oxidation state.…”

“… 51 TiO 2 nanomaterials, especially in the anatase phase, display antibacterial activity but they have limited inhibition to the growth of antibiotic-resistant bacteria. 52 , 53 Doping of TiO 2 enhances not only photocatalytic activity but also improves the antibacterial properties of TiO 2 nanomaterials, even in the absence of a light source. Moongraksathum et al synthesized TiO 2 co-doped with silver and ceria, and they found high antimicrobial activity against E. coli and S. aureus both under UV light and dark conditions.…”

In this study, TiO 2 -based ceramic nanofiber membranes in the system of TiO 2 −SiO 2 −Al 2 O 3 −ZrO 2 −CaO− CeO 2 were synthesized by combining sol−gel and electrospinning processes. In order to investigate the thermal treatment temperature effect, the obtained nanofiber membranes were calcined at different temperatures ranging from 550 to 850 °C. Different characterization methods such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), and high-resolution transmission electron microscopy (HR-TEM) were conducted on the obtained membranes to investigate the structural and morphological properties of the nanofibers. The Brunauer−Emmett−Teller surface area of the nanofiber membranes was very high (46.6−149.2 m 2 /g) and decreased with increasing calcination temperature as expected. Photocatalytic activity investigations were determined using methylene blue (MB) as a model dye under UV and sunlight irradiation. High degradation performances were achieved with the calcination temperatures of 650 and 750 °C because of the high specific surface area and the anatase structure of the nanofiber membranes. Moreover, the ceramic membranes showed antibacterial activity against Escherichia coli as a Gram-negative bacterium and Staphylococcus aureus as a Gram-positive bacterium. The superior properties of the novel TiO 2 -based multi-oxide nanofiber membranes proved as a promising candidate for various industries, especially the removal of textile dyes from wastewater.

“…The incorporation of metal nanoparticles into the coatings generated by PEO also improves the surface’s antibacterial properties. For instance, Ag nanoparticles-decorated TiO 2 -based coatings on titanium exhibited bactericidal effects against E. coli and S. aureus bacteria strains [ 116 ]. Zhou et al [ 117 ] linked the antibacterial mechanism ( E. coli and S. aureus ) of the W-containing coating on the surface of Ti 6 Al 4 V alloy formed by PEO with the reactive oxygen species (ROS).…”

“…Ion release presents one of the most important factors affecting cell/material interaction and biomineralization. Ions can inhibit the bacteria by damaging their envelope and cytoplasmic component, blocking the peptidoglycan ability to transfer oxygen, inactivation of enzymatic functions of proteins, and/or disrupting the DNA replication [ 116 ]. In this case, the most efficient plasma treatment techniques are based on coating technologies (e.g., PIII&D and PEO).…”

Bacterial infections of medical devices present severe problems connected with long-term antibiotic treatment, implant failure, and high hospital costs. Therefore, there are enormous demands for innovative techniques which would improve the surface properties of implantable materials. Plasma technologies present one of the compelling ways to improve metal’s antibacterial activity; plasma treatment can significantly alter metal surfaces’ physicochemical properties, such as surface chemistry, roughness, wettability, surface charge, and crystallinity, which all play an important role in the biological response of medical materials. Herein, the most common plasma treatment techniques like plasma spraying, plasma immersion ion implantation, plasma vapor deposition, and plasma electrolytic oxidation as well as novel approaches based on gaseous plasma treatment of surfaces are gathered and presented. The latest results of different surface modification approaches and their influence on metals’ antibacterial surface properties are presented and critically discussed. The mechanisms involved in bactericidal effects of plasma-treated surfaces are discussed and novel results of surface modification of metal materials by highly reactive oxygen plasma are presented.
