Confocal laser scanning microscopy of MDA-MB-231 cancer cells incubated with a DCA-UiO-DTDP-FA + Sulfo-Cy5.5 and b DCA-UiO-DTDP + Sulfo-Cy5.5 for 1, 6, and 16 h at 37 °C. Each series shows cell nuclei (dyed blue with DAPI for visualization), DCA-UiO-DTDP-FA + Sulfo-Cy5.5 or DCA-UiO-DTDP + Sulfo-Cy5.5, and a merging of the two images. The scale bar in each image is 20 μm
