Fig. 5From: Quantum dots as targeted doxorubicin drug delivery nanosystems in human lung cancer cellsViability of human lung carcinoma cells (A549) treated with QDs coated with MUA (a), Cys (b), LA (c), and QDs (d) functionalized with FA and DOX and free DOX. Data were obtained from three independent experiments (n = 6). ****P < 0.0001 vs. A549 cells treated with 50 µg·mL−1 of QD–MUA and QD–MUA–FA (unpaired t-test).
