The cantilever amplitude maps are the basic signal used to derive the elastic moduli, see eqs (1) and (2). This amplitude is shown here because of its better visualization (it has better contrast of small features to demonstrate lateral resolution). (a–c) A blend of two polymers (low density polyethylene and polystyrene). (d–f) Corneocyte sample. (a,d) Height, (b,e) cantilever amplitude (d), and (c,f) the cross-sections of the cantilever amplitude are shown. The smallest features resolved in these images are of the order of 50 nm for polymers and 70 nm for the corneocytes sample.
