应用

Hyaluronic acid (HA) is a linear polysaccharide of alternating D-glucuronic acid and N-acetyl-D-glucosamine found primarily in connective tissues. HA based hydrogels are widely used in tissue engineering, 3D bioprinting, and drug deliery applications. The methacrylate functionalized hyaluronic acid is photo-crosslinkable, and can be used to generate crosslinked hydrogels.
