“…It was reported that the antimicrobial activity is due to the diffusion of surface ions from the catalysts, which provoke the destruction of the membrane of microbial species. Wadge et al [211] have studied the antibacterial activity of GaTiO3 against Staphylococcus Aureus in dark. The authors reported that Staphylococcus aureus showed a high resistance compared to other pathogenic species (e.g., A.…”

“…Wadge et al [266] assessed the potential viability of Ga-ion-exchanged titanate, produced using a 4 mM Ga(NO 3 ) 3 ion-exchange solution (more biocompatible compared to GaCl 3 ; FDA approved for cancerassociated hypercalcemia treatment), against S. aureus, a less susceptible pathogenic species. The Ga titanate structures tested would not leach enough Ga 3+ ions (4-40 μM) into solution to have an antibacterial effect on S. aureus (Figure 25).…”

Improving the surface of medical implants by plasma spraying of a hydroxyapatite coating can be of critical importance to their longevity and the patient's convalescence. However, residual stresses, cracking, undesired crystallisation and delamination of the coating compromise the implants lifetime. A promising alternative surface application is an alkali-chemical treatment to generate bioactive surfaces, such as sodium and calcium titanate and their derivatives. Such surfaces obviate the need for high temperatures and resulting micro-crack formation and potentially improve the bioactive and bone integration properties through their nanoporous structures. Also, metallic ions such as silver, gallium and copper can be substituted into the titanate structure with the potential to reduce or eliminate the infections. This review examines the formation and mechanisms of bioactive/antibacterial alkaline titanate surfaces, their successes and limitations, and explores the future development of implant interfaces via multifunctional titanate surfaces on Ti-based alloys and on alternative substrate materials.

“…In addition to antibacterial properties, the bioactivity of the material was also improved. A hydrothermal ion-exchange process on porous sodium titanate allows sufficient penetration of Ga(NO 3 ) 3 solution into the surface structure [ 147 ]. Similar surface coating was applied to 3-D printed titanium implants [ 148 ].…”
