Multifunctional hydrogels for chronic wounds repairing

Because of their tissue-like mechanical performances,high biocompatibility,and adjust-able functionality,hydrogels have become increasingly attractive materials for promoting wound healing.Chronic wounds include burn,diabetic,and infected wounds.Unlike common incision wounds,chronic wounds are more challenging to heal.To meet the clinical needs,multifunctional hydrogels should be fabricated and investigated.To guide future studies on the fabrication of hydrogel-based chronic wound dressings,a review of advanced multifunctional hydrogels is necessary.Various hydrogels with advanced properties,such as antibacterial,antioxidant,bioadhesive,anti-inflammatory,and wound healing properties,that can be used for skin burn wounds and diabetic wounds are summarised.Lastly,the prospects of advanced hydrogels for wound healing are elaborated.
