Summary:[Display omitted] •The SA-CD double-layer hydrogel was fabricated using green synthesized carbon dots.•Carbon dots can improve water swelling, vapor transmission rate, and mechanical properties.•SA-CD double-layer hydrogel is biocompatible, hemostatic, and flexible. In this study, a new double-layer sodium alginate (SA) hydrogel was fabricated using green synthesized carbon dots (CDs). The Urtica dioica was used as a natural precursor to synthesize CDs. The casting/solvent evaporation process was employed to fabricate SA-CD double-layer hydrogel. The properties of the SA-CD double-layer hydrogel were examined, including morphology, swelling, water vapor permeability, mechanical and rheological properties. The results show that SA-CD double-layer hydrogels are biocompatible, hemostatic, and flexible. They also have adequate water swelling, a high rate of water vapor transmission, and better mechanical properties, which make them candidates for biomedical applications such as wound dressing.
