Photothermal therapy (PTT) has become a candidate treatment for breast cancer due to its non-invasive, specific and controllable properties. However, there are few strategies to develop photothermal agents with high photothermal conversion efficiency, adequate tumor accumulation, and the molecular design theory is not perfect. Thus, to obtain the photothermal agent with better comprehensive performance
光热疗法(PTT)因其非侵入性、特异性和可控性而成为乳腺癌的候选治疗方法。然而,开发光热转换效率高、肿瘤蓄积充足的光热剂的策略很少,而且分子设计理论也不完善。因此,为了获得综合性能更好的光热剂,一种新型共轭聚合物PAPQ-Th,其包含喹喔啉衍生物10,11-双(4-(辛氧基)苯基)苊并[1,2-b]吡嗪并[2,3-设计并合成了g]喹喔啉(PAPQ)作为受体,噻吩(Th)作为供体。 PAPQ-Th表现出7.3×1011 s−1的高非辐射率和微弱的荧光发射。 PAPQ-Th 纳米颗粒在 650 nm 至 900 nm 范围内表现出强烈的近红外吸收,ROS 的产生可以忽略不计,并且在 808 nm 激光照射下具有高达 61% 的光热转换效率。此外,PAPQ-Th纳米颗粒可成功用于体外和体内实验,并表现出显着的光热抗肿瘤功效。经过静脉注射和808 nm激光照射后,4T1荷瘤小鼠肿瘤达到完全缓解,没
