Abstract

Water soluble fluorescent nanocrystals were obtained by encapsulation of hydrophobic quantum dots (QDs) with amphiphilic phospholipids derived from the ring opening metathesis of norbornene-based monomers. The robustness of the newly coated quantum dots was assessed by comparative studies under various ionic conditions which indicated an overall enhancement of their fluorescence stability.

摘要

通过用源自降冰片烯基单体开环易位反应的两亲性磷脂包裹疏水性量子点（QDs），获得了水溶性荧光纳米晶体。通过在各种离子条件下的对比研究评估了新包覆量子点的稳定性，结果表明其荧光稳定性总体增强。
