Figure 2. — Nanocrystalline diamond film with 200 μm wide H/O-terminated patterns: (a) optical (bright field) image prior to cell plating showing optically transparent and featureless surface, (b) scanning electron microscopy image prior to cell plating where bright stripes correspond to H-termination and dark stripes to O-termination of the diamond surface due to their opposite electron affinity, (c) fluorescent microscopy image of osteoblastic cells cultivated on the substrate. The alignment cross is used for correlation of the surface termination micro-patterns with the cells.
