Curcumin-Loaded Silver-Based Metal-Organic Frameworks: Efficient Antibacterial and Antioxidant Properties against and for Promoting Infected Wound Healing.

Slow or noticeably delayed wound healing is frequently intimately linked to bacterial infection and excessive reactive oxygen species (ROS), while the inappropriate usage of antibiotics fuels the rise of bacterial resistance. The innovative materials are desperately needed to eliminate bacteria and effectively accelerate wound healing. In this work, a curcumin-loaded silver-based metal-organic framework (Cur/Ag-MOF) composite nanomaterial was developed, which exhibited good antimicrobial activity, biocompatibility, and drug resistance. Meanwhile, surface-loaded curcumin can effectively eliminate excess free radicals and promote wound healing due to its antioxidative and ROS scavenging properties. Additionally, it was discovered that the application of Cur/Ag-MOF to the site of skin trauma significantly sped up the process of wound closure in mice used as subjects. These findings highlighted its great potential for treating bacterial infection-induced skin injuries and aiding the healing and reconstruction of skin tissues.
