Figure 2From: Investigation of size–dependent cell adhesion on nanostructured interfaces Scanning electron micrographs of polymeric nanopillar arrays made of UV-curable adhesive. The diameters of the nanopillars are (a) 214 ± 13 nm, (b) 322 ± 16 nm, (c) 425 ± 17 nm, (d) 500 ± 19 nm, and (e) 684 ± 17 nm. Scale bars are 1 μm.Back to article page
