Inorganic-Nanomaterial-Composited Hydrogel Dressings for Wound Healing

Abstract

Wound management heavily relies on the vital contribution of wound dressings, emphasizing the significance of finding an ideal dressing that can fulfill the intricate requirements of the wound healing process with multiple functions. A promising strategy is combining several materials and therapies to create multifunctional wound dressings. Nanocomposite hydrogel dressings based on nanomaterials, combining the advantages of nanomaterials and hydrogels in wound treatment, can significantly improve their respective performance and compensate for their shortcomings. A variety of nanocomposite wound dressings with diverse structures and synergistic functions have been developed in recent years, achieving ideal results in wound management applications. In this review, the multiple functions, advantages, and limitations of hydrogels as wound dressings are first discussed. Additionally, the application of inorganic nanomaterials in wound healing is also elaborated on. Furthermore, we focused on summarizing and analyzing nanocomposite hydrogel dressings for wound healing, which contain various inorganic nanomaterials, including metals, metal oxides, metal sulfides, carbon-based nanomaterials, and silicon-based nanoparticles. Finally, prospects for nanocomposite hydrogel wound dressings are envisaged, providing insights for further research in wound management.

Multihydrogen Bond Modulated Polyzwitterionic Removable Adhesive Hydrogel with Antibacterial and Hemostatic Function for Wound Healing

“…After functional modification, the adhesive strength of the zwitterionic hydrogels was up to 4 KPa. Clinical treatment of wounds requires consideration of a variety of factors, including wound depth, size, cause of injury, patient complications, and wound physiology. , Proper application of dressings under the guidance of a medical professional with experience in wound care can help patients heal faster. In clinical applications, suitable adhesion allows the hydrogel to protect the wound and allow for painless removal, which reduces patient pain.…”
