制备了一系列聚糖包被的量子点,以探测HeLa和SV 40上皮细胞中聚糖呈递在细胞内定位中的作用。我们发现聚糖密度主要影响细胞毒性,而聚糖类型影响细胞摄取和细胞内定位。此外,我们表明乳糖可以作为双功能化QD上的“特洛伊木马”,以帮助细胞内递送其他不可内化的聚糖部分,并在很大程度上避免内体/溶酶体降解途径。
A series of glycan‐coated quantum dots were prepared to probe the effect of glycan presentation in intracellular localization in HeLa and SV40 epithelial cells. We show that glycan density mostly impacts on cell toxicity, whereas glycan type affects the cell uptake and intracellular localization. Moreover, we show that lactose can act as a “Trojan horse” on bi‐functionalized QDs to help intracellular delivery of other non‐internalizable glycan moieties and largely avoid the endosomal/lysosomal degradative pathway.
