摘要

通过双溶剂交换法制备了包裹铯硼三纳米晶体的聚乙二醇共轭磷脂胶束。该方法首次应用于CsPbBr3包晶石的胶束封装，避免了纯化步骤。所制备的样品具有很高的溶解度，即使在水中浸泡五天后仍能保持很高的光致发光性能。更重要的是，磷脂胶束对 CsPbBr3 纳米晶体的封装大大提高了人氦宫颈癌细胞（Hela 细胞）的成像效率。

Phospholipid micelles-encapsulated perovskite nanocrystals via dual solvent exchange for human hela cervical cancer cells imaging

Polyethylene glycol-conjugated phospholipid micelles encapsulated CsPbBr₃ nanocrystals were prepared through dual solvent exchange method. This strategy was applied for the first time to micellar encapsulation of CsPbBr₃ perovskites, circumventing the purification step. The as-prepared sample showed high solubility and maintained high photoluminescence performance even after five days in water. More importantly, the encapsulation of phospholipid micelles toward CsPbBr₃ nanocrystals greatly improved the imaging efficiency of human hela cervical cancer cells (Hela cells).
