Abstract

Hypoxia, excessive reactive oxygen species (ROS), impaired angiogenesis, lasting inflammation, and bacterial infection, are key problems impeding diabetic wound healing. Particularly, controllable oxygen release and ROS scavenging capacities are critical during the wound healing process. Here, an injectable hydrogel based on hyaluronic acid-graft-dopamine (HA-DA) and polydopamine (PDA) coated Ti3C2 MXene nanosheets is developed catalytically cross-linked by an oxyhemoglobin/hydrogen (HbO2/H2O2) system combined with mild photothermal stimulation for diabetic wound healing. HbO2 not only acts as a horseradish peroxidase-like to catalyze the hydrogel formation but also as an oxygen carrier to controllably release…
