Abstract
Diabetic wounds are increasingly common and challenging to treat due to high infection risks in a high-glucose environment. Effective treatment requires wound dressings that combat infections, while promoting angiogenesis and skin regeneration. This study presents a hydrogel-based drug delivery system made from cellulose designed to accelerate diabetic wound healing by eliminating bacterial infections. The hydrogel, formed by linking phenylboronic acid-grafted oxidized methylcellulose (POMC) with poly(vinyl alcohol) (PVA), exhibits self-healing and injectable properties. It is further enhanced by adding type I recombinant human collagen (rhCOL1) to stimulate cell growth and angiogenesis and mesoporous zinc oxide (mZnO) for antibacterial and anti-inflammatory effects. Upon application, the hydrogel degrades under pH/ROS stimuli, releasing mZnO and rhCOL1 in a controlled manner that matches the wound healing stages. In vivo tests show that the hydrogel effectively eliminates bacteria, reduces inflammation, and promotes rapid skin regeneration, making it a promising solution for treating diabetic wounds.
