Title: Nanostructure and strength in collagen biomaterials

Abstract:

Collagen is the main component of many robust natural materials and some manufactured materials. The strength of the material is normally one of the key properties required in technological applications. The basis for strength in collagen materials is not fully understood. We use small angle X-ray scattering to investigate the collagen fibril arrangement and structure in leather, pericardium, and surgical scaffold materials. The structure isrelated to the physical properties of these materials. This is combined with atomic force microscopy, histology, electron microscopy and ultrasonic imaging. We discover a complex relationship between strength and a number of structural factors including fibril orientation, fibril diameter and cross linking. These can be related to tissue type, species, age of the animal and processing conditions. This has lead to some useful technological applications.This talk will describe some of our recent ideas and discoveries in this area.
