Recent advances in hyaluronic acid hydrogels for biomedical applications

- New modifications to hyaluronic acid (HA) enable both covalent crosslinking and supramolecular assembly.
- Composite HA hydrogels permit controlled drug delivery and mechanical toughness.
- Processing such as electrospinning, 3D printing, and photopatterning allow the formation of complex structures in HA hydrogels.
- HA hydrogels are engineered to influence the fate of encapsulated or endogenous cells.
- HA hydrogels continue to advance basic science and translational biomedical research.
