AFM images (1 μm × 1 μm) of a SAM on a gold substrate with DTPA to glycan ligand 1 ratios of a 500:1 and b 2500:1. Scale bars, 200 nm. c Box plots of the height profiles for the small particles observed in the AFM images (10 ≤ n ≤ 20). Statistical significance was determined based on one-way ANOVA with Dunnett’s multiple comparisons test (****P < 0.0001)
