Flow cytometer analysis for cell proliferation assay of carboxyfluorescein succinimidyl ester (CFSE)-labelled U251 upon treatment with EDT-IONPs, DOX and DOX-EDT-IONPs. (a) CFSE flow cytometry graph, and (b) the relative cell proliferation inhibition calculated by (mean CFSE control/mean CFSE treated). *Shows a significant difference compared to the control group at p < 0.05. IONPs and DOX-IONPs represent for EDT-IONPs and DOX-EDT-IONPs.
