Photodynamic therapy (PDT) has received increasing attention in disease treatment due to its minimally-invasive, selective destruction with a combination of a photosensitizer (PS), light, and oxygen. However, the limited cytotoxic singlet oxygen (1O2) generation and thin tissue penetrability have been two major barriers in conventional PDT, hindering its further development and clinical use. Recently, fluorescence resonance energy transfer-based drug delivery systems (FRET-DDSs), indirectly activating PS drugs by a donor fluorophore, have been successfully applied to alleviate these issues. The transfer of excitation energy from donors to PS drugs can significantly boost its light harvesting and extend the field of the light source, which dramatically improves its production efficiency of 1O2, thus leading to highly efficient and deep-tissue-penetrable PDT for the treatment of bacteria, cancer and other diseases. In this Review, we give the first-known overview of recent advances in FRET-DDSs for enhanced PDT. In particular, dependent on the excitation energy mechanism in the FRET process, six major types of FRET-DDSs, including one-photon, two-photon, upconversion, auto-fluorescence, X-ray, and Cerenkov excited FRET-DDSs, in PDT applications are summarized in detail. Furthermore, future research directions and perspectives in this emerging field are also discussed.

基于荧光共振能量转移的药物递送系统,用于增强光动力治疗。

由于光动力疗法(PDT)通过光敏剂(PS),光和氧气的组合进行的微创,选择性破坏,因此在疾病治疗中受到越来越多的关注。但是,有限的细胞毒性单线态氧(1O2)产生和薄组织穿透性已成为常规PDT的两个主要障碍,阻碍了其进一步的开发和临床应用。最近,通过供体荧光团间接激活PS药物的基于荧光共振能量转移的药物递送系统(FRET-DDS)已成功应用于缓解这些问题。将激发能从供体转移到PS药物上可以大大促进其光的采集并扩展光源的视野,从而极大地提高其1O2的生产效率,因此,导致了用于细菌,癌症和其他疾病的高效,深层可穿透性PDT。在这篇评论中,我们对增强PDT的FRET-DDSs的最新进展给出了第一个已知的概述。特别是,取决于FRET过程中的激发能机理,PDT中有六种主要类型的FRET-DDS,包括一光子,两光子,上转换,自发荧光,X射线和切伦科夫激发的FRET-DDS。详细总结了应用程序。此外,还讨论了该新兴领域的未来研究方向和前景。在PDT应用中,对包括单光子,双光子,上转换,自发荧光,X射线和切伦科夫激发的FRET-DDS进行了详细总结。此外,还讨论了该新兴领域的未来研究方向和前景。在PDT应用中,对包括单光子,双光子,上转换,自发荧光,X射线和切伦科夫激发的FRET-DDS进行了详细总结。此外,还讨论了该新兴领域的未来研究方向和前景。
