Figure 6

Scanning electron microscopy images showing the adhesion (after 24 h) and proliferation (after 72 h) of L929 murine fibroblasts on the surface of Ti6Al4V alloy and TNT/Ag coatings produces in PEALD process with 25 cycles (TNT3/25, TNT10/25, TNT15/25, TNT20/25) observed after 24 h (a–e) and 72 h (f–j) of incubation time, respectively. Figure (k) presents rounded shape of the cells incubated with Ti6Al4V reference sample for 24 h in comparison to the more elongated shape of the fibroblasts incubated with TNT3/25 (l) and TNT10/25 (m) for the same time period. Arrows in the figure indicate the filopodia spread between cells (l,m) or penetrating deep into the nanolayers (n,o).
