Fig. 6

SEM images of MDCK cells after 7-day growth on the substrates. The different substrates presented the following: a Si, b Si + Au, and cf Si + Au + ZnO urchin2. a, b A confluent layer of cells was formed on the surface of both the reference materials (cell growth was not affected). cf Individual cells rather than a confluent layer are present on the Si + Au + ZnO urchin 2 nanostructured substrate. Note: A layer of proteins (either from cell culture medium, or from cell debris) is formed around the individually attached cells
