Fig S1. AFM height image of potato starch after adding and removal a drop of water. Scan size: 5 µm × 5 µm, height scale: 10 nm. The solution of the gelatinized starches (10 µl) was dropped hot onto a newly cleaved mica surface by a pipette, dried by nitrogen, followed by adding 10 µl water to the surface. Then the water was removed 2 min later by Kimwipes carefully, dried by nitrogen, and a height image was captured.
