美国和澳大利亚研究人员开发可生物降解的和智能的伤口补丁,以便更好的慢性伤口愈合。 U.S. and Australian researchers develop biodegradable and smart wound patches for better chronic wound healing.

密西西比大学的研究人员正在开发三维印印的可生物降解的慢性伤口补丁,使用天然材料,如Chitosan和植物抗微生物剂,以促进愈合和预防感染,同时又不产生抗生素抗药性。 Researchers at the University of Mississippi are developing 3D-printed, biodegradable patches for chronic wounds using natural materials like chitosan and plant-based antimicrobials to promote healing and prevent infection without causing antibiotic resistance. 定制的补丁在身体中溶解,避免清除和刺激,并有利于偏远或军事环境。 The custom-fit patches dissolve in the body, avoiding removal and irritation, and could benefit remote or military settings. 另外,澳大利亚研究人员在水凝中用碳点制造了一个智能伤口敷料,通过pH变化检测感染,显示智能手机上可见的颜色变化,并自动释放纳米酶以对抗炎症。 Separately, Australian researchers created a smart wound dressing with carbon dots in a hydrogel that detects infection via pH changes, showing color shifts visible on smartphones, and automatically releases nanozymes to fight inflammation. 该补丁也可以手动激活 。 The patch can also be manually activated. 这两项技术都旨在改善慢性创伤护理,促成早期干预,并与数字保健系统融合,尽管在临床使用前还需要进一步测试和监管批准。 Both technologies aim to improve chronic wound care, enable early intervention, and integrate with digital health systems, though further testing and regulatory approval are needed before clinical use.
