Effect of carrying out a temperature cycle on a 10% w/w dispersion of PEG₁₁₃-PHPMA₃₀₀ vesicles. TEM images obtained for (a) spherical micelles after cooling in ice for 1 h; (b) smaller vesicles after warming to 50 °C for 24 h; (c) large, polydisperse vesicles initially obtained after synthesis; (d) DLS size distributions obtained for the respective samples after dilution to 0.1% w/w; (e) centrifuge tube containing sedimented PEG₁₁₃-PHPMA₃₀₀ vesicles loaded with fluorescently poly[(2-methacryloyloxy)ethyl phosphorylcholine].
