This study developed a curcumin-loaded chitosan hydrogel to treat Staphylococcus aureus-infected wounds. The novel biomaterial effectively promoted skin healing by reducing inflammation and enhancing tissue repair.
Area of Science:
- Biomaterials Science
- Wound Healing Research
- Infectious Disease Treatment
Background:
- Bacterial infections impede wound healing.
- Curcumin offers therapeutic potential but requires effective delivery.
- Chitosan hydrogels are promising biomaterials for drug delivery.
Purpose of the Study:
- To develop and evaluate a curcumin-loaded chitosan-based hydrogel for infected wound healing.
- To investigate the hydrogel's properties and efficacy against Staphylococcus aureus.
- To explore the mechanisms underlying accelerated skin repair.
Main Methods:
- Fabrication of a curcumin-loaded chitosan hydrogel using phenylborate ester bonding.
- Assessment of the hydrogel's antioxidant properties.
- In vitro testing against Staphylococcus aureus growth.
- In vivo evaluation of infected wound healing in a skin model.
Main Results:
- The hydrogel demonstrated significant antioxidant activity against intracellular reactive oxygen species.
- Effective inhibition of Staphylococcus aureus growth was observed.
- Accelerated infected skin healing was achieved, attributed to inflammation regulation, enhanced angiogenesis, and collagen synthesis.
Conclusions:
- The developed multifunctional hydrogel is a promising therapeutic agent for infected wound healing.
- Curcumin delivery via chitosan hydrogel effectively combats S. aureus infections.
- The hydrogel's properties support tissue regeneration and reduce healing time.
