This systematic review examines light-activated polysaccharide hydrogels for osteoarthritis (OA) repair, highlighting their structural regulation, gelation principles, and controlled release properties. The review establishes that the density of polysaccharide functional groups influences crosslinking density and mechanical properties, which are crucial for effective drug delivery and tissue regeneration in OA treatment.
Key findings
- The density of polysaccharide functional groups governs the grafting of light-responsive moieties.
- Crosslinking density and mechanical properties are dictated by the structural regulation of the hydrogels.
- Photothermal materials and polysaccharide modifications regulate release kinetics for OA treatment.
Why it matters
Understanding the mechanisms of light-activated polysaccharide hydrogels can enhance local drug delivery and tissue regeneration strategies in osteoarthritis, potentially improving patient outcomes and reducing side effects associated with traditional therapies.
