From: The role of intracellular trafficking of CdSe/ZnS QDs on their consequent toxicity profile
Plots from the intracellular trafficking profile of QDs in HFF-1 cells using early endosomes-GFP, and lysosomes-GFP. a Images showing an example of the (i) overlay of NH2-QDs with the lysosomal marker, (ii) the tracks for the green lysosomal channel, (iii) tracks for the QD channel, and (iv) colocalization of green (lysosomal) and red (QD) tracks. The scale bar corresponds to 5 μm. b, c Graphs represent trajectory-based dynamic colocalization of fluorescent NH2-QDs with the endosomal marker (Rab5a) and lysosomal marker (LAMP1) that was calculated and plotted as a function of time. Each dot corresponds to 1 min movie recording that was taken in different cells at that specific time point
