small molecule two-photon (TP) fluorescent probe (CCNa1) was developed for mitochondrial sodium ion sensing. CCNa1 exhibits a low solvatochromic shift and strong TP fluorescence enhancement at 575 nm upon binding to Na+ and is insensitive to other metal ions and to pH. CCNa1 demonstrated fast cell loading ability, biocompatibility, and sensitive response to mitochondrial Na+ influx in live cells and mouse
开发了一种基于环花青 (CC) 的有机小分子双光子 (TP) 荧光探针 ( CCNa1 ),用于线粒体钠离子传感。CCNa1与 Na +结合后在 575 nm 处表现出低溶剂化变色和强 TP 荧光增强,并且对其他金属离子和 pH 不敏感。CCNa1表现出快速的细胞加载能力、生物相容性以及对活细胞和小鼠脑组织中线粒体 Na +流入的敏感反应。
