Characterization of tetrablock copolymer and resulting self-assembled polymersomes in phosphate buffered saline (PBS). (a) 1H NMR spectrum of PEG17-PPS28-PBI-PPS28-PEG17 in CDCl3. (b) GPC traces of PEG17-PPS28-PBI-PPS28-PEG17 and PEG17-PPS28 copolymers. (c) CryoTEM image of 1:1 PEG17-PPS28-PBI-PPS28-PEG17 : PEG17-PPS28 polymersomes in PBS at a concentration of 10 mg/mL (scale bar = 100 nm). (d) Dynamic light scattering (DLS) measurement of the polymersome size distribution in PBS (1 mg/mL). The averaged diameter is 60 nm with PDI = 0.220.
