Synergistic healing of diabetic wounds through photothermal and peroxidase-like activity of heterogeneous Bi2S3/Au nanoparticles

/Au NPs significantly inhibit the formation of biofilms caused by bacteria, and promote the deposition of collagen and the formation of epithelial and dermal tissue. This study provides a promising solution for innovative therapy of refractory diabetic wounds, which is of great significance for reducing the abuse of antibiotics and the production of drug-resistant bacteria.
