Figure 2From: Mapping out the structural changes of natural and pretreated plant cell wall surfaces by atomic force microscopy single molecular recognition imagingAFM topography and recognition images of natural plant cell walls. Topography (a-f) and recognition (g-l) images of natural poplar (P), switchgrass (SG), and corn stover (CS). (a, c, e, g, i, k) show the representative surface area mainly covered by lignin and (b, d, f, h, j, l) show the representative surface area mainly covered by crystalline cellulose.Back to article page
