主 题:collagen type I collagen laminates rose bengal and green light crosslinking thickness analysis micro tensile testing cell-collagen interactions
摘 要:Collagen is one of the most important biomaterials for tissue engineering *** its excellent biocompatibility,it shows the non-negligible disadvantage of poor mechanical *** crosslinking with rose bengal and green light(RGX)is an appropriate method to improve this *** development of collagen laminates is helpful for further adjustment of the mechanical properties as well as the controlled release of incorporated *** this study,we investigate the impact of crosslinking and layering of two different collagen scaffolds on the swelling behavior andmechanical behavior inmicro tensile tests to obtain information on its wearing comfort(stiffness,strength and ductility).The mechanical stability of the collagen material after degradation due to cell contact is examined using thickness *** is no linear increase or decrease due to layering homologous ***,a decrease in elongation at break,Young’s modulus and ultimate tensile strength are measured when the untreated monolayer is compared to the crosslinked ***,we can detect a connection between stability and cell *** results show that with variation in number and type of layers,collagen scaffolds with tailored mechanical properties can be *** a multi-layered structure enables the release of biomolecules into inner or outer layers for biomedical applications.
