The electron beam irradiation of type I bovine collagen gels: Insights into radiation dose and water content impacts on the composition and the structural, rheological, thermal and mechanical properties
Original language description
This study examined the impacts of electron beam irradiation (0.25, 0,5, 1, 10 and 25 kGy) on bovine collagen hydrogels at a concentration of 3 wt%. The impact of irradiation was verified via the analysis of the mechanical, thermal and rheological properties, changes in the composition and structure of the collagen, its stability in the enzymatic environment, and its swelling and morphology. Both the degradation and cross-linking of the collagen mass were demonstrated in relation to the radiation dose. Degradation was proven via a decrease in the content of the triple helical part of the collagen and transformation into other collagen structural states, and cross-linking was demonstrated by an increase in the network chain density with the radiation dose. When compared with the non-irradiated gels, no significant qualitative changes in the configuration or ordering over longer distances were evident following the application of the irradiation doses. The apparent elastic modulus, overall thermal stability and rheological characteristics in the oscillatory regime, and the storage and loss moduli of elasticity correlated positively with the radiation dose.
