Fig. 4. STEM-EDS elemental maps of a single DTC-micelle, isolated after incubation in cisplatin solution at pH 7 and 37 °C for 2 d. The concentrations for DTC and cisplatin are 20 and 200 μM, respectively, during the incubation. Red, green, blue, yellow, and cyan signals represent characteristic emissions from C, O, S, Fe, and Pt elements, respectively. The scale bar represents 50 nm.
