Developing a material that can combat antibiotic‐resistant bacteria, a major global health threat, is an urgent requirement. To tackle this challenge, we synthesized a multifunctionalsubphthalocyanine (SubPc) polymer nanosphere that has the ability to target, label, and photoinactivate antibiotic‐resistant bacteria in a single treatment with more than 99 % efficiency, even with a dose as low as 4
迫切需要开发一种可以抵抗抗生素耐药性细菌的材料,这是对全球健康的主要威胁。为了应对这一挑战,我们合成了多功能亚酞菁(SubPc)聚合物纳米球,该纳米球能够在一次处理中以99%以上的效率靶向,标记和光灭活抗生素耐药性细菌,即使剂量低至4.2 J cm -2和10 n M的负载浓度。由共价连接的SubPc单元组成的带正电的纳米球壳可以增加光敏剂在治疗部位的局部浓度。与相应的单体相比,纳米球表现出优越的性能,大概是因为它们具有增强的水分散性,更高的单线态氧生成效率和光毒性。另外,该材料可用于活细胞的荧光标记,并在体内细菌的光声成像中显示出希望。
