Abstract

This research explores the efficacy of photodynamic therapy (PDT) and photothermal therapy (PTT) in combating chemotherapy-resistant diseases. This study focuses on enhancing tumor treatment effectiveness by leveraging the synergetic effects of combining PDT and PTT through the development of Fe-nitrogen-carbon (FeNC) nanoparticles with superior photostability. These nanoparticles, functioning as photosensitizers for the combined PDT/PTT treatment, can generate both type I and type II ROS and heat upon 808 nm irradiation. Notably, the FeNC nanoparticles demonstrate an exceptional photothermal conversion efficiency (34 %), surpassing commonly used PTT photosensitizers. In vitro and in vivo experiments corroborate the efficiency of FeNC as a photosensitizer in achieving significant tumor inhibition. In conclusion, the FeNC nanoparticles present promising applicability in the synergistic PTT/PDT treatment of tumors.

含有原子分散铁原子的 FeNC 作为光敏剂用于光动力和光热联合疗法

这项研究探讨了光动力疗法（PDT）和光热疗法（PTT）在抗化疗耐药疾病中的疗效。本研究的重点是通过开发具有优异光稳定性的碳氮铁（FeNC）纳米粒子，利用光动力疗法和光热疗法的协同效应提高肿瘤治疗效果。这些纳米粒子是 PDT/PTT 联合治疗的光敏剂，在 808 纳米波长的照射下可产生 I 型和 II 型 ROS 和热量。值得注意的是，FeNC 纳米粒子显示出卓越的光热转换效率（34%），超过了常用的 PTT 光敏剂。体外和体内实验证实，FeNC 作为光敏剂可有效抑制肿瘤。总之，FeNC 纳米粒子在 PTT/PDT 协同治疗肿瘤方面具有广阔的应用前景。
