Photo-Responsive Phase-Separating Fluorescent Molecules for Intracellular Protein Delivery.Cellular membranes, including the plasma and endosome membranes, are barriers to outside proteins. 
Photo-Responsive Phase-Separating Fluorescent Molecules
The PPFM compound condensates as fluorescent droplets in the aqueous solution by liquid-liquid phase separation (LLPS), which disintegrate upon photoirradiation with a 405 nm LED lamp within 20 min or a 405 nm laser within 3 min.
