Functionalization of nanoridges with collagen IV. (A–C) Side-view images of the fluorescent-collagen-coated nanoridges reconstructed from z-stack confocal images. The planes are perpendicular to the surface in the position of the dashed lines in (D) of the color of the image borders. (D) Top-view schematic of nanoridges with grey representing the ridges. Scale bars, 3 μm.
