Multifunctional chitosan-copper-gallic acid based antibacterial nanocomposite wound dressing

Antibacterial wound dressings can effectively avoid the residual of antibacterial nanomaterials for injection in vivo, reduce their biological toxicity to normal cells and tissues, making them be widely applied in biomedical field. Herein, an approach of combining ion-crosslinking, in-situ reduction and microwave-assisted methods was employed to prepare chitosan-copper-gallic acid nanocomposites (CS-Cu-GA NCs) with dual-functional nano-enzyme...
