Dynamic light scattering was used to measure Z-average diameter (mean diameter based on intensity of scattered light and sensitive to presence of large particles), peak diameter, peak width and polydispersity index (PdI). PFCE = perfluoro-15-crown-5-ether; X = mole fraction; PE = phosphoethanolamine; DPPE = 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine; POPE = 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoethanolamine; DSPE-PEG2000 = 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N[methoxy(polyethylene glycol)-2000.
