MXenes‐based flexible electronics for wound monitoring and treatment

Abstract Wound healing is a dynamic and overlapping bio‐process with varied cellular and molecular characteristics involved. Traditional wound dressings have made significant achievements in accelerating wound healing; however, they lack the ability to monitor the dynamic changes of wounds, which limits the effectiveness of wound management. Currently, the development of flexible electronics‐based intelligent dressings that can monitor wound characteristics in a real‐time manner can make a positive impact on clinical practice. MXenes, also known as a type of 2D inorganic compound, are generally considered ideal precursors for fabricating flexible electronics. MXenes‐based flexible electronics can not only monitor the biomarkers of wounds (e.g., temperature, pH, lactic acid) but also promote wound healing by combining with other bio‐activities. This review begins with a brief introduction to the challenges associated with the early diagnosis of wounds. It then provides a comprehensive summary and discussion of the fabrication and applications of MXenes‐based flexible electronics for wound monitoring and treatment. Finally, it explores the current challenges and future directions in this cutting‐edge field.
