A Carbodiimide Cross‐Linked Silk Fibroin/Sodium Alginate Composite Hydrogel with Tunable Properties for Sustained Drug Delivery

Carbodiimide cross‐linked silk fibroin (SF)/sodium alginate (SA) composite hydrogels with superior stability and tunable properties are developed by varying preparation parameters. SF/SA blend ratio modulation allows to achieve composite hydrogel gelation times of 18–65 min, and rheological analysis shows that the speed of gel formation, the hydrogel network's density, and the hydrogels’ compressive properties are closely related to the blend...
