Summary
A novel porous composite material combats drug-resistant bacteria by combining photocatalysis and nanozyme activity to generate reactive oxygen species. This advanced antibacterial strategy also promotes skin wound healing.
Area of Science:
- Materials Science
- Nanotechnology
- Biomedical Engineering
Background:
- Rising threat of multidrug-resistant pathogens necessitates non-antibiotic antibacterial strategies.
- Existing ROS-based photocatalysis and nanozyme systems face limitations like charge recombination and low efficiency.
Purpose of the Study:
- To develop a composite heterostructure for enhanced antibacterial activity and wound healing.
- To investigate the synergistic effects of photocatalysis and nanozyme catalysis in a novel material.
Main Methods:
- Fabrication of a porous C3N4@oxygen-vacancy-rich CoFe-LDH quantum-dot (p-CN@CF-O) composite.
- Characterization of material properties and defect engineering.
- In vitro and in vivo evaluation of antibacterial efficacy and wound healing in a skin infection model.
Main Results:
- The p-CN@CF-O composite exhibited enhanced ROS generation and efficient charge separation due to synergistic effects.
- The material demonstrated potent antibacterial activity against drug-resistant pathogens and suppressed biofilm formation.
- In vivo studies showed accelerated wound healing and effective bacterial eradication.
Conclusions:
- The developed composite heterostructure offers a promising non-antibiotic strategy for combating bacterial infections and promoting skin regeneration.
- This work highlights the potential of defect-engineered materials for synergistic photocatalysis-nanozyme antibacterial applications.
