33342 upon single wavelength excitation. Compared to conventional organelle stains, the two AIE probes have larger Stokes shifts and higher photostability, which endow them with the capability to monitor bioprocesses, such as mitophagy with strong and sustained fluorescent signals. Moreover, both probes can also stain intracellular organelles in zebrafish larvae with good cell-penetrating capabilities,
为了揭示细胞功能,使用单波长激发的多路细胞器成像是非常需要的,但是仍然具有挑战性。这需要设计具有不同发射但具有相似吸收的细胞器特异性荧光团。在本文中,我们提出了两种独特的聚集诱导发射(AIE)探针,可同时跟踪线粒体和溶酶体,并且发射颜色可以与单波长激发下的核染色剂Hoechst 33342区别开来。与传统的细胞器染色剂相比,这两种AIE探针具有更大的斯托克斯位移和更高的光稳定性,这使它们具有监测
生物过程的能力,例如具有强且持续荧光信号的线粒体。而且,体内。
