Abstract
A rhodamine-based probe (FS1) was synthesized and its fluorescence properties and application to an iron-overloaded cell line demonstrated. FS1 underwent fluorogenic changes by the Fe(3+)-catalyzed reaction, even in the presence of other metal cations in vitro. Chemodosimeter FS1 demonstrated selective and sensitive detection of intracellular Fe(3+) in hepatocytes.
摘要
合成了一种基于罗丹明的探针（FS1），并研究了其荧光性质及其在铁过载细胞系中的应用。FS1 通过 Fe(3+) 催化反应发生荧光变化，即使在体外存在其他金属阳离子时也是如此。化学传感器 FS1 能够选择性和灵敏地检测肝细胞内的 Fe(3+)。
