Collagen fibrils size distribution

Parry, D. A. D., Barnes, G. R. G., and Craig, A. S. (1978). A comparison of the size distribution of collagen fibrils in connective tissues as a function of age and a possible relationship between fibril size distribution and mechanical properties. Proc. Roy. Soc. Lond. B. 203, 305-321. 

The surface structure of collagen fibril is visually described using the SEM, AF M, and TEM observations. The ultrastructure of collagen fiber is quantitatively described using the pore size distribution calculated from adsorption isotherms. The former depends on the achievements of other researchers. The latter is mainly my work. It is regrettable that the SEM or AFM observation cannot be compared with the pore size distribution on the same collagen sample. The functions of micropores inside the collagen in the native state must be elucidated.
