a Uptake of DOX loaded micelles (DOX-M) on MCF-7 cells. The photos were taken with a fluorescent microscopy. Cells pre-treated to produce more ROS were incubated with drug loaded micelles (DOX-M(S)). The nuclei were stained as blue, localization of DOX was red and their merged pictures were also showed. b Normalized fluorescence per cell analysed by Photoshop software (n = 3)
