Typical surface characterization images of the AR-Ti and HTE-Ti surfaces.

(a) High resolution optical profilometry images of the AR-Ti and HTE-Ti surfaces over a scanning area of 46.7 μm × 62.3 μm along with height profiles, indicating the presence of sharp nanowires on the surface of the HTE-Ti. (b) Representative SEM images of the AR-Ti and HTE-Ti samples (Scale bar 400 nm). (c) Wettability of AR-Ti and HTE-Ti surfaces in terms of their water contact angles.
