Development of an activated ratiometric indicator that is specific to plasma membrane (PM) viscosity exhibits great application prospects in disease diagnosis and treatment but remains a great challenge. Herein, a photo-activated fluorescent probe (CQ-IC) was designed and prepared tactfully, which could analyze and real-time monitor the microenvironmental homeostasis of the PM based on a two-channel ratiometric imaging model. Interestingly, upon light irradiation, CQ-IC generates reactive oxygen species and thus increases the cellular viscosity, which increases two emission peaks at 480 and 610 nm. This work would propose a new strategy to sensor PM homeostasis and effectively guide the treatment of viscosity-related diseases among various physiological and pathological processes.
开发特异性质膜(PM)粘度的活化比率指示剂在疾病诊断和治疗中具有广阔的应用前景,但仍是一项巨大的挑战。本文设计并巧妙制备了一种光活化荧光探针(CQ-IC),该探针可基于双通道比率成像模型分析并实时监测质膜的微环境稳态。有趣的是,在光照射下,CQ-IC 会产生活性氧,从而增加细胞粘度,使 480 和 610 纳米波长处的两个发射峰增加。这项工作将提出一种新的策略来传感 PM 的平衡,并有效指导各种生理和病理过程中与粘度相关疾病的治疗。
