- Abstract
- Cutaneous wounds accompanied by massive bleeding, bacterial infections might be lethal and cause fundamental therapeutic impediments in clinical fields. As part of the push for a solution, biomaterial having hemostatic antibacterial features is highly desirable. Inspired by this concept, freeze dried sponges were developed followed by combining tempo-oxidized nanocellulose (TOCN), chitosan using EDC/NHS cross-linker with antibacterial lawsone loading for controlled delivery of this compound during wound healing. The pore diameter decreased upon increasing chitosan (2.5, 3.5, 4.5, 5.5% w/v) while TOCN ensured scaffold's mechanical stability. The in vitro degradation, lawsone release from fibroblast cell-compatible sponge was faster in acidic pH 5.5 than physiologic pH 7.4 indicating adaptability to physiological skin milieu of wounds. The rat tail amputation model, 14 days rat full-thickness cutaneous-wound model ensured hemostasis, dramatic wound closure after TLC4.5 (optimized scaffold) treatment suggesting its potential as functional wound healing substitute showing obvious avenue for hemostatis and skin tissue reconstruction arena.
