Fig. 2
AFM morphological analysis of control and nanostructured surfaces produced by SCBD. The images show representative a top views and b 3-dimensional views of the surfaces morphology of glass coated with poly-l-lysine (PLL), flat zirconia (flat-Zr) produced by e-beam evaporation, and nanostructured zirconia (ns-Zr) produced by SCBD with Rq = 15 (ns-Zr15), or 25 nm (ns-Zr25), respectively. c The graphs display a comparison of representative topographic profiles of different substrates
