Figures & data
Figure 1. Morphological changes of J774A.1 macrophage cells after the engulfment of PFC emulsions manufactured by (b) EYP and (c) RF-PEG 8000, respectively. The cells shown in (a) were the normal cells without the treatment of PFC emulsions. Compared with EYP-mediated PFC emulsions, the degree of phagocytosis was ameliorated to a large extent for RF-PEG 8000 mediated ones. Photomicrographs were taken after 9-h incubation (Magnification × 100).
Figure 2. 19F-NMR spectrum of FC-40 emulsions. The CF3 absorption peak of the FC-40 was located at −86.2 ppm.
Figure 3. 19F-NMR spectra of fluorine contained within the macrophages that engulfed emulsified PFC microparticles made by EYP and RF-PEG 8000, respectively. All the chemical shifts were referenced to the internal standard CF3SO3Na at −81.4 ppm.
