Ultrastrong and Flexible Hybrid Hydrogels based on Solution Self-Assembly of Chitin Nanofibers in Gelatin Methacryloyl (GelMA)

We demonstrate ultrastrong and flexible hydrogels by self-assembling chitin nanofiber in the presence of gelatin methacryloyl. We tune the mechanical properties of the hydrogel with chitin nanofiber content and show proof-of-concept applications in engineering vascular tissue.
