Fig. 6From: Polyethylene terephthalate nanoparticles effect on RAW 264.7 macrophage cellsPET-NPs internalization (magnification). TEM micrograph detailed magnification from Fig. 5-F, of PET-NPs internalized by RAW 264.7 cell line (F1, F2, F3, F4). Yellow squares indicate the sequence of magnification zone and white arrows point out the planar distance of PET semicrystalline (F4), and its FTT diffraction pattern (G)Back to article page
