Collagen Ink for 3-D Bioprinting
January 30, 2018 | Terry Sharrer
Biochemists at Rutgers University have shown how to 3-D print scaffolds for tissue culture and regenerative medicine using a chemically treated collagen ink. They accomplished this with “functionalized lysine residues of type-I collagen with methacrylate groups to form collagen methacrylamide, or CMA. CMA retains the triple helical nature of type-I collagen and the ability to self-assemble into fibers and a fibrillar hydrogel. CMA is also photolabile and can be crosslinked in its fibrous form by exposure to UV-initiated free radicals.” Scaffolds made this way can be freeze dried for future use. MORE
