Percentage of wound closure area plotted over time for QD–MUA–FA–DOX, QD–Cys–FA–DOX, QD–MUA–LA–DOX, and free DOX at the final IC50 concentration. Data were obtained from three independent experiments and presented as mean ± SD. *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 doxorubicin
