Modified titanium nanotubes (TiO2NTs) coatings are grown in simulated body fluid (SBF) from Ticp and Ti6Al4V. The addition of 1% v/v of SBF to the electrolyte neither modifies film morphology nor the structural oxide characteristics for both metal substrates. However, an improvement in mechanical properties (hardness and elasticity model) and wettability is observed. From bioactive assay, a higher amount of fl
