Efficacy of cisplatin-loaded vesicles. Comparison of cell growth at time 0, 24, 48, and 72 h for A549 cells with no treatment (black), treated with empty vesicles (gray), with cisplatin-loaded vesicles (purple), and free cisplatin in solution (pink). Empty vesicles have no effect on cell growth while both free cisplatin and loaded vesicles show similar efficacy in killing A549 cells. Each data point is the average of five experiments. A Student’s t-test was used to determine significance. The asterisk “*” indicates a p value of <.001.
