Hydrogen peroxide (H2O2) as a reactive oxygen species (ROS) plays a crucial role in oxidative stress and signal transduction of organisms. Currently, a fluorescence probe has proven to be a powerful tool for the H2O2 analysis. However, the common problem is the slow response, causing difficulty in tracking H2O2 in situ. Herein, we describe a novel aggregation-induced emission (AIE) fluorescence probe based on increased polarity of C-B bonds that is well suited for monitoring H2O2 rapidly and selectively. Importantly, the probe was successfully applied to visualize H2O2 levels in living cells, which provides a rapid-response and highly selective fluorescence tool for monitoring of the H2O2 levels in biological process.
过氧化氢(H₂O₂)作为一种活性氧(ROS),在生物体的氧化应激和信号转导中起着至关重要的作用。目前,荧光探针已被证明是用于H₂O₂分析的强大工具。然而,常见的问题是响应缓慢,导致原位跟踪H₂O₂存在困难。在此,我们描述了一种基于C-B键极性增加的新型聚集诱导发光(AIE)荧光探针,它非常适合快速、选择性地监测H₂O₂。重要的是,该探针已成功应用于可视化活细胞中的H₂O₂水平,这为监测生物过程中的H₂O₂水平提供了一种快速响应且高度选择性的荧光工具。
