Figure 4From: Mapping out the structural changes of natural and pretreated plant cell wall surfaces by atomic force microscopy single molecular recognition imagingTopography and recognition images of natural, dilute acid pretreated, and delignified corn stover cell wall. Topography (a-d, i-l) and recognition (e-h, m-p) images of natural, dilute acid pretreated (pretreated by 0.03%, 0.5%, and 1% sulfuric acid at 135°C) and delignified corn stover cell wall. Some residues in (d) which do not have recognitions in (h) are highlighted in the red circles.Back to article page
