Fig. 1

Representative TEM micrographs of a PLLA35-b-PDMAEMA315 spherical micelles prepared via a solvent switch from N,N-dimethylformamide to water, (Dh = 149 nm, PD = 0.245 as obtained by dynamic light scattering), b PLLA35-b-PDMAEMA315 platelets (length = 893 ± 100 nm, width = 528 ± 60 nm as measured using ImageJ from TEM micrographs) prepared via CDSA, heating the polymer solution in EtOH at 90 °C for 2 h, and c PLLA35-b-PDMAEAm400 cylindrical micelles prepared via CDSA (length = 300 ± 52 nm, width = 10 ± 1 nm as measured using ImageJ from TEM micrographs). Samples were stained with 1% uranyl acetate. Scale bar = 1000 nm for a and c, 500 nm for b.
