Multimodal imaging-guided photothermal therapy (PTT), for the therapy of cancer, based on a ferritin (FRT) nanocage loaded with the near-infrared dye IR820 (designated DFRT) is demonstrated. The dual roles of DFRT (in imaging and PTT) are successfully balanced by using two different excitation wavelengths: 550 nm for high quantum-yield fluorescence imaging on the one hand and 808 nm for photoacoustic imaging and PTT with high photothermal conversion efficiency on the other.
本文展示了一种基于负载近红外染料IR820的铁蛋白(FRT)纳米笼(命名为DFRT)用于癌症治疗的多模态成像引导光热疗法(PTT)。通过使用两种不同的激发波长,成功平衡了DFRT的双重作用(成像和PTT):一方面,550 nm用于高量子产率荧光成像;另一方面,808 nm用于光声成像和具有高光热转换效率的PTT。
