a–c Typical three-dimensional AFM images of IA-Chol films with polystyrene spheres (D = 250 nm) on the surfaces exposed to the light for 2, 3 and 5 min, respectively. d–g Top-view SEM images of IA-Chol films with polystyrene spheres (D = 1000 nm) on the surfaces exposed to the light for 10, 20, 30, and 60 min, respectively. h, i Side-view SEM images of IA-Chol films with polystyrene spheres (D = 1000 nm) on the surfaces exposed to the light for 20 min and 30 min. The light intensity and wavelength were 300 mW cm−2 and 488 nm. The scale bars of all the SEM images correspond to 2 μm.
