Abstract:

Some of the wound dressings on the market cause skin tearing and bleeding when removed, slowing the healing process. So, it is difficult to treat infected wounds of sensitive skin patients. Herein, antibacterial and biocompatibility self-healing hydrogel loaded with 9-Aminoacridine and kanamycin sulfate were prepared by grafting poly(β-carboxyethyl acrylate-co-acrylamide) onto sodium alginate. The biological assay demonstrated the hydrogels’ good biocompatibility, which showed no harmful effects on normal human melanocyte cells. In addition, the hydrogels had a powerful antibacterial impact on the various bacterial strains utilized in the investigation. From the study of the rheological properties of the prepared hydrogel, it was found that it is a non-Newtonian fluid. These results suggest the possible utilization of the as-prepared hydrogels in the fabrication of wound healing.
