Atomic force microscopy (AFM) images of algal cellulose gravity-deposited on hydrophobically silanized glass imaging surfaces. a 50 × 50 µm2 field of view (scale bar = 10 µm), and b 5 × 5 µm2 field of view (scale bar = 1 µm). White circle in a highlights particles seen on the surface. Individual fibril heights ranged from ~ 3 to 6 nm
