A-F) AFM was used to detect the elastic modulus and diameter of AF and NP collagen fibers. G) Representative AFM images of collagen fibrils in AF and NP. A-B) Nanoscale measurement of the elastic modulus of a single collagen fiber in AF. The diameter of AF is shown in Fig. D and E, and the elastic modulus and diameter of NP are shown in Fig. C and F: (#) represents significant difference compared with other groups except Group B (p < 0.05). (&) represents significant difference compared with other groups except Group A (p < 0.05). (*) indicates statistical significance between the two groups (p < 0.05). (+) indicates statistical significance between the two groups (p < 0.0001).
