Fig. 7From: Quantum dots as targeted doxorubicin drug delivery nanosystems in human lung cancer cellsNumber of colonies made of 2–10 human lung carcinoma cells (A549) treated with QD–MUA–FA–DOX, QD–Cys–FA–DOX, and QD–LA–FA–DOX. Data were obtained from three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001, between the studied concentrations (unpaired t-test). QD Ag–In–Zn–S nanocrystals modified with: 11-mercaptoundecanoic acid (MUA), Cys L-cysteine, LA lipoic acid, FA folic acid, DOX doxorubicinBack to article page
