Chinese scientists have designed a new biodegradable and bioactive material that can enhance wound-healing and skin regeneration. 中国科学家设计了一种新的生物降解和生物活性材料，可以促进伤口愈合和皮肤再生。 It is difficult for skin wounds to completely heal in cases of large-area burns, severe microbial infections and diabetes. Chronic wounds greatly increase the pain and medical costs of patients. 在大面积烧伤、严重微生物感染和患有糖尿病的情况下，皮肤伤口很难完全愈合。慢性创伤极大地增加了病人的痛苦和医疗费用。 There is therefore a great need for biomedical materials that can facilitate wound-healing and efficient anti-infection capacities. 因此，非常需要能够促进伤口愈合和有效抗感染能力的生物医学材料。 |
