Charge-switchable, anti-oxidative molecule tuned polyelectrolyte multilayered films: Amplified polyelectrolyte diffusivity and accelerated diabetes wound healing

The local oxidizing microenvironment and bacterial infection, as crucial internal and external factors that hinder the healing of diabetic wounds, are two main issues to be addressed in the design of novel wound dressing materials. As an attempt to provide optimal solution to the aforementioned problems, free-standing (FS) polyelectrolyte multilayer films (PEMs) loaded with bis[2-(4-hydroxyphenyl) benzimidazole] (BHPB) were constructed by...
