Study of the structure and the molecular mobility of a new biological matrix (collagen/peptides)

The thermal analyses have showed a slight decreasing of the denaturation temperature for all the treated collagens. These results suggest a slight destabilization of treatments on the collagen triple helix. The dielectric results highlight the probable crosslinking effect of irradiation between the collagen and the peptides with a chain dynamics similar to the pure collagen one. Indeed, it is known that irradiation can cause a crosslink effect. These preliminary analyses are quite promising for the conception of a new type of biological matrix. In order to optimize the properties of this new material, analyses will be made with less harmful ultraviolet irradiation.
