AI Article Synopsis
- Developed a new photoswitchable fluorophore called PEG-PMI-DTE that is both amphiphilic and resistant to fatigue.
- The fluorophore allows for significant changes in fluorescence and shows bistable photochromism.
- It can be used to visualize small liposome structures under super-resolution fluorescent microscopy with a high optical resolution of 30 nm.
Article Abstract
We have designed and synthesized an amphiphilic photoswitchable fluorophore, PEGylated perylenemonoimide-dithienylethene (PEG-PMI-DTE), which exhibits evident bistable photochromism, fluorescence switching, and fatigue resistance. The fine nanostructures of liposomes can be observed directly under super-resolution fluorescent microscopy by aid of the amphiphilic photoswitchable fluorophore as a staining agent, with an optical resolution of 30 nm.
