AFM images of immobilized particles: (a) silica NPs (120 nm), (b) silica NPs (120 nm), (c) silica NPs (470 nm), (d) silica NPs (35 nm), (e) PS NPs (28 nm). Samples were prepared on the PAAm-PFPA surface except for (a), which was prepared on PFPA-silane surface. The inserts in all graphs are topographic scale bars.
