Injectable and self-healing hydrogel containing nitric oxide donor for enhanced antibacterial activity

The wound bacterial infections have become an intractable problem to human health. Multifunctional wound dressing materials with excellent adhesion, antibacterial as well as wound healing properties are still desperately needed to resist wound infection. In this work, an injectable hydrogel has been prepared, which chitosan and hyaluronic acid were cross-linked by aldehyde modified polyethylene glycol (PEG). For improving the antibacterial...
