Silk sericin (SS), a biocompatible protein derived from silkworms, exhibits valuable properties for medicinal applications, including antioxidant activity and cell growth support. However, their rapid degradation limits practical use. This study introduces silver ions (Ag+) as dual-function cross-linking agent to enhance the structural functional of SS-based hydrogels. The incorporation Ag+ stabilized hydrogel network through dityrosine cross-links coordination bonds with SS amino acid side...
