“…The obtained porous SWNTs show a morphology very similar to bone tissue structures. The new, additionally produced top SWNTs layer is designed to accelerate the osseointegration process, reduce the risk of the releasing of harmful compounds from the implant into the body, and the occurrence of inflammation [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 25 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 48 , 49 ]. In line with the latest trends in implantology, the layer of oxide nanotubes can be a carrier for drugs delivered to a specific location and enable their controlled release into the body at a specific rate, depending on the size of the SWNTs [ 12 , 29 , 41 ].…”

“…Innovative methods of obtaining multifunctional chitosan-based coatings on the smooth and porous surface of the Ti-13Zr-13Nb alloy using the electrophoretic deposition method (EPD) have been developed [ 18 ]. It has been reported that composite chitosan-copper nanoparticles obtained by a one-step EPD with the addition of a dispersing agent reveal strong adhesion, high corrosion resistance, and improved mechanical and antimicrobial properties [ 20 ]. Composite chitosan-nanosilver coatings obtained by cataphoretic deposition are characterized by increased surface bioactivity and antibacterial properties [ 21 ].…”

In the group of vanadium-free titanium alloys used for applications for long-term implants, the Ti-13Zr-13Nb alloy has recently been proposed. The production of a porous layer of oxide nanotubes (ONTs) with a wide range of geometries and lengths on the Ti-13Zr-13Nb alloy surface can increase its osteoinductive properties and enable intelligent drug delivery. This work concerns developing a method of electrochemical modification of the Ti-13Zr-13Nb alloy surface to obtain third-generation ONTs. The effect of the anodizing voltage on the microstructure and thickness of the obtained oxide layers was conducted in 1 M C2H6O2 + 4 wt% NH4F electrolyte in the voltage range 5–35 V for 120 min at room temperature. The obtained third-generation ONTs were characterized using SEM, EDS, SKP, and 2D roughness profiles methods. The preliminary assessment of corrosion resistance carried out in accelerated corrosion tests in the artificial atmosphere showed the high quality of the newly developed ONTs and the slight influence of neutral salt spray on their micromechanical properties.
