Studysummary This study developed a novel hydrogel dressing, QL@MAB, which facilitates accelerated healing of infected diabetic wounds in rats by offering prolonged drug release, water retention, and adaptive drug delivery in response to high glucose levels in the wound environment. Our plain-language summary of this paper — not a Tressless recommendation.
The study presents a novel hydrophobic hydrogel, QL@MAB, designed for diabetic wound therapy. This hydrogel is composed of hydrophobic methyl acrylate and (3-acrylamidophenyl)boronic acid, co-loaded with antioxidant quercetin and antibiotic levofloxacin. The hydrogel mimics skin structure, with hydrophobic segments forming a dense "epidermis" for prolonged drug diffusion and water retention, while glucose-labile "sweat pores" facilitate drug release in hyperglycemic conditions. In diabetic rats, QL@MAB promotes rapid wound healing, angiogenesis, hair follicle regeneration, and extracellular matrix remodeling, showcasing its potential as a multifunctional dressing for diabetic wounds.
