我们报告说，牛血清白蛋白（BSA）包被的量子点可以用作荧光探针，用于测量一个单一的活细胞的细胞质粘度：荧光相关光谱测量的HeLa细胞将BSA量子点显示，细胞质的粘度是4.7倍大于水。
We report that bovine serum albumin (BSA)-coated quantum dots can be used as a fluorescent probe for measuring the cytoplasmic viscosity of a single living cell: fluorescence correlation spectroscopy measurements for a HeLa cell incorporating BSA-quantum dots show that the viscosity of cytoplasm is 4.7 times greater than that of water.
