A dressing with antibacterial drugs loaded onto aramid nanofibers hydrogels was developed to accelerate wound healing in bacterial infected wounds. The hydrogels had good mechanical properties, high water content, high water adsorption property, and good water retention ability. In vivo results showed that the composite hydrogels accelerated the healing rate of infection wounds and were suitable as potential anti-infective wound dressings.
Bacterial infections severely retard the wound healing process. Antibacterial drugs were loaded onto aramid nanofibers (ANFs) hydrogels through a convenient strategy to fabricate dressings for bacterial infected wound healing. ANFs hydrogels owned good mechanical properties, high water content (>98%), high water adsorption property (>10,000%) and good water retention ability (a water retention of >5000% after incubating at RH 30% for 8 h), capable to absorb and retain the wound exudate to form a moist environment. The incorporation of antibacterial drugs promised the ANFs hydrogels with durable antibacterial properties. Furthermore, the drug loaded ANFs hydrogels had no cytotoxicity nor hemolytic potential. In vivo skin wound healing results confirmed that the composite hydrogels accelerated the healing rate of infection wounds on mice and were suitable as a potential anti-infective wound dressing.
