BaTiO3 Doping Enhances Ultrasound-Driven Piezoelectric Bactericidal Effects of Fibrous Poly(L-Lactic Acid) Dressings to Accelerate Septic Wound Healing

Bacterial invasion in infected skin wounds triggers inflammation and impedes healing. Current therapeutic strategies incorporating drug interventions within wound dressings often result in drug resistance and delayed healing. Here, we developed a comprehensive therapeutic modality integrating piezoelectric fibrous dressing with controlled ultrasound stimulation for efficient healing in an infected wound model. The electrospun fibrous dressings composed of barium titanate (BaTiO
