Fig. 4From: Polyethylene terephthalate nanoparticles effect on RAW 264.7 macrophage cellsMito-ID confocal images from RAW 264.7 cells incubated in presence of PET-NPs. Merge image showed the nucleus (Hoechst) and the Mito-ID signalling for both control and cells incubated with PET-NPs. Mito-ID signal have not showed significant difference between control and PET-NPs. After incubation for 72 h, big lysosomes were easily observed (black arrow)Back to article page
