From: Replica-mold nanopatterned PHEMA hydrogel surfaces for ophthalmic applications
Hydrogel surface with cultured human fibroblasts (scale bars 100 µm). Phase-contrast image (a) shows the surface with the nanopillar array (white rectangle); the sputtered arrow shape (see Fig. 1) is covered by the cell marked by the yellow rectangle. Image (b) shows the detail of the area (green rectangle) consisting of unmodified hydrogel surface (top half) and nanopattern (bottom half) with the corresponding bright-field image given in (c).
