Wearable Magnetoelectric Stimulation for Chronic Wound Healing by Electrospun CoFe₂O₄@CTAB/PVDF Dressings

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(8), P. 9839 - 9853

Published: Feb. 19, 2024

Magnetoelectric stimulation is a promising therapy for various disorders due to its high efficacy and safety. To explore potential in chronic skin wound treatment, we developed magnetoelectric dressing, CFO@CTAB/PVDF (CCP), by electrospinning cetyltrimethylammonium bromide-modified CoFe2O4 (CFO) particles with polyvinylidene fluoride. Cetyltrimethylammonium bromide (CTAB) serves as dispersion surfactant CFO, quaternary ammonium cations imparting antibacterial hydrophilic properties the dressing. Electrospinning polarizes fluoride (PVDF) molecules forms fibrous membrane flexibility breathability. With wearable electromagnetic induction device, dynamic magnetic field established induce magnetostrictive deformation of CFO nanoparticles. Consequently, piezoelectric generated on surface PVDF nanofibers enhance endogenous electrical wound, achieving cascade coupling electric–magnetic–mechanical–electric effects. Bacteria cell cultures show that 2% CTAB effectively balances property fibroblast activity. Under stimulation, CCP dressing demonstrates significant upregulation TGF-β, FGF, VEGF, promoting L929 adhesion proliferation. Moreover, it facilitates healing diabetic rat wounds infected Staphylococcus aureus within 2 weeks. Histological molecular biology evaluations confirm anti-inflammatory effect accelerated formation collagen vessel stimulation. This work provides insights into application wounds.
