Wound dressing
Oct 16, 2023
Wound dressing has been an important branch of biomedical materials research.Skin damage caused by abrasion after falling and clinical incision after surgery are the most common wounds in real life.Compared with the wounds at flat areas of human body, it is still challenging to treat the wounds at special areas such as joints, popliteal fossae, axillae, and muscle folds. Poor adhesive performance, difficult fixation, and incomplete coverage are the main reasons. Moreover, in clinic, most wounds are sterilized with 75% alcohol or iodine, followed by covering with cotton gauzes. Therefore, regular disinfection and dressing replacement are necessary due to lack of antibacterial property of cotton gauze. In addition, fixed cotton gauze dressing needs to be taped, and sometimes, the skin is allergic to tape material. To this end, designing a stretchable, adhesive, antibacterial, and biocompatible dressing is of great clinical significance. Hydrogels are a class of 3D network gels formed by ...
