Manipulation of Surface Electrical Charge on Nanocomposite Membranes Confers Wide Spectrum Bactericidal Effects and Promotes Tissue Regeneration

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(22)

Published: Feb. 5, 2024

Abstract Utilization of electro‐responsive biomaterials with antibacterial properties is advantageous for facilitating septic wound healing and tissue regeneration. However, the dose‐response effects electrical stimuli from these materials against bacteria are not rigorously characterized, achieving synergy bactericidal pro‐regenerative remains a major challenge. Here, graded series flexible BaTiO 3 /P(VDF‐TrFE) electroactive nanocomposite membranes (EMs) developed varying surface charge intensities, to serve as dressing healing. EMs display broad‐spectrum both Gram‐positive Gram‐negative in dose‐dependent manner, depending on magnitude their potential. Mechanistically, increase intracellular levels reactive oxygen species within cells, which turn caused oxidative damage bacterial membrane, thereby suppressing activity biofilm formation. Moreover, vivo studies demonstrated that effectively inhibited S. aureus infection accelerated mouse skin defect model, well ameliorated P. gingivalis‐ mediated periodontal inflammation periodontitis model. Hence, this study optimizes characterizes bacteria, thus validating therapeutic applications combating infection.
