Biomimetic nano dressings have superior biological activity, biocompatibility, and stimuli-responsive properties compared with traditional wound dressings due to their biomimetic design integration and show great potential in wound management. This review summarizes the materials and techniques used to prepare current biomimetic nano dressings, focusing on biomimetic design strategies. Moreover, we explore the application of biomimetic nano dressings in treating wounds associated with infections, burns, diabetes, and postoperative skin cancer. This review provides new perspectives on the design of biomimetic nano dressings and highlights future research directions to further advance innovative wound treatment strategies.
