Fig. 3. Confocal fluorescence images of (a–d) MDA-MB-231 cells incubated with Rh-T (10 μM) and stained with DiD (20 μM); and (e–h) MDA-MB-231 cells incubated with Nph-A/Rh-T (1 : 1, Nph-A = 10 μM and Rh-T = 10 μM) and stained with DiD (20 μM). 3D confocal images of channel 1 (red) of the MDA-MB-231 cells incubated with (i–m) Nph-A/Rh-T (1 : 1, Nph-A = 10 μM and Rh-T = 10 μM) and (n–r) Rh-T (= 20 μM). Scanned from bottom to top. Channel DiD: excitation: 640 nm, emission collected: 663–738 nm. Channel 1 for Rh-T: excitation: 561 nm, emission collected: 570–620 nm. Scale bar: 10 μm.
