“…The values shown represent the mean of several indentations performed on multiple substrates, and there was no sign of delamination of anodic film on any of the substrates. Notably, as compared to popular anodized Ti nanostructures like titania nanotubes (TNTs), [ 121 ] all nanostructures obtained in the current study exhibited superior modulus and elasticity. A gap between individual structures in anodized Ti with nanotubes makes them prone to strain and fracture under loading conditions.…”

“…The results show that stable nanostructures can be obtained on Ti‐based implants using anodization optimization (modified anodization parameters, use of micro‐patterned substrates, electrolyte aging and single‐step anodization) and various physical and chemical enhancements, as reviewed recently. [ 121 ] Our group is at the forefront of optimizing anodization to fabricate robust anisotropic nanopores on micro‐rough Ti via single‐step anodization in an aged (repeatedly used) electrolyte. [ 16d,41 ] Interestingly, as compared to nanopores (which already exhibit superior mechanical characteristics as compared to conventional nanotubes or physically/chemically enhanced nanotubes [ 32b,121 ] ), the nanostructures fabricated in the current study showed higher Young's modulus (>100 GPa at 50 nm indentation depth).…”

Typically, the modulus for anisotropic nanopores ranges from 80–110 GPa and hardness 4–6 GPa (at 50 nm indentation depth).…”

Bioinspired titanium implant nanotexturing achieved via advanced techniques such as lithography, hydrothermal and laser patterning enables modulation of cell functions toward enhanced bioactivity and antibacterial efficacy. However, such costly, multi‐step methods limit clinical translation and benchtop implant modification. For the first time, single‐step, cost‐effective, and translatable electrochemical anodization is reported to fabricate bioinspired nanopillar‐like textures on micro‐rough titanium. In‐depth surface characterization confirms the formation of novel nanostructures, namely nanoscale Spinules, Daggers, Papillae, Spikes, and Flames, exhibiting varied roughness and wettability. Next, in separate experiments, primary human osteoblasts and polymicrobial salivary biofilm are cultured on the implant substrates. Nanotextured surfaces show high protein adhesion and maintain the proliferation, adhesion, and spreading of osteoblasts. Interestingly, all nanotextures exhibit superior antibiofilm abilities compared to control surfaces. Bioactive and antibacterial implant surface nano‐texturing achieved via single‐step anodization has the potential for clinical translation as the next generation of orthopedic and dental implant surface modification.
