Fig. 3. WT NR6 cell adhesion is enhanced through nanoscale RGD clustering even when average peptide density remains the same. Cell adhesion strengths on most clustered (5.4 RGD/comb) and least clustered RGD (1.7 RGD/comb) substrates are compared at three comparable RGD surface densities. (A) 5.4 RGD/comb: 1050 RGD/µm²; 1.7 RGD/comb: 1660 RGD/µm². (B) 5.4 RGD/comb: 530 RGD/µm²; 1.7 RGD/comb: 830 RGD/µm². (C) 5.4 RGD/comb: 260 RGD/µm²; 1.7 RGD/comb: 330 RGD/µm².
