制备了一系列葡聚糖包被的量子点,以探讨葡聚糖提呈对HeLa和SV40上皮细胞内定位的影响。我们发现,多糖密度主要影响细胞毒性,而多糖类型影响细胞摄取和细胞内定位。此外,我们发现乳糖可以作为双功能量子点上的“特洛伊木马”,帮助其他非内在化的糖链部分在细胞内传递,并在很大程度上避免内体/溶酶体的降解途径。
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.
