systems for cancer therapy. However, it is difficult to track traditional liposome delivery systems in an efficient and stable fashion to assess their delivery efficacy and biodistribution after administration. Meanwhile, conventional fluorescent liposomes containing optical tracers face the challenge of aggregation‐caused quenching. Herein, we report a strategy for the integration of an aggregation‐induced
脂质体已经被用作用于癌症治疗的流行的药物递送系统。然而,难以以有效和稳定的方式追踪传统脂质体递送系统以评估其在给药后的递送功效和生物分布。同时,包含光学示踪剂的常规荧光脂质体面临着聚集引起的猝灭的挑战。本文中,我们报道了一种将聚集诱导的发射氟与脂质体整合以产生称为“ AIEsome”的AIEgen-脂质缀合物的策略。AIEsome表现出鲜红色的荧光以及出色的光稳定性和生物相容性,可用于体外癌细胞标记和体内肿瘤靶向。同时,得益于AIEgen出色的光敏能力以及在水性介质中的良好氧气暴露,
