Researchers developed an injectable hydrogel system combining GHK-Cu with carbon dots to treat radiation-induced skin injuries. The smart delivery system releases antioxidants first to combat oxidative stress, then releases GHK-Cu in a sustained manner to promote tissue repair and collagen formation. In vitro and in vivo testing showed the combination effectively accelerated healing of radiation-damaged skin by addressing both the inflammatory and regenerative phases of wound healing. This represents a novel dual-phase approach using GHK-Cu for clinical wound management.
