Supplementary material from "PEGylated Phospholipid Micelles-Encapsulated CsPbBr₃ Nanocrystals Obtained via Dual Solvent Exchange for HeLa Cell Imaging"

Polyethylene glycol-conjugated phospholipid micelles encapsulated CsPbBr₃ nanocrystals were prepared through dual solvent exchange method. This strategy was, to the best of our knowledge, applied for the first time to micellar encapsulation of CsPbBr₃ perovskites, circumventing the purification step. The as-prepared sample showed high solubility in water and maintained high photoluminescence performance even after five days in water. More importantly, the encapsulation of phospholipid micelles towardCsPbBr₃ nanocrystals greatly improved the imaging efficiency of HeLa cells.<br>
