An injectable self-healing coordinative hydrogel with antibacterial and angiogenic properties for diabetic skin wound repair
In this work, an injectable, self-healing hydrogel with antibacterial and angiogenic abilities was prepared based on the coordination of multi-arm thiolated polyethylene glycol (SH-PEG) with antibacterial silver ions (Ag+). The injectable and self-healing properties derive from the dynamic nature of the Ag-S coordination bonds. After incorporation of an angiogenic drug desferrioxamine (DFO), we could obtain a multifunctional hydrogel with manageable, resistant to external stress, antibacterial and angiogenic properties. Such unique multifunctional hydrogel thus shows potential to accelerate the healing of some exposed wounds (e.g., diabetic skin wound) under disturbed physiological functions, high risk of bacterial infections, and external mechanical irritation
