a Apparent size of PEG-PA, PEG-PAO, and PEG-PAS aqueous solutions (0.01 wt.%) at 20 °C. b Transmission electron microscopy images of PEG-PA, PEG-PAO, and PEG-PAS micelles developed from their aqueous solution (0.01 wt.%). The scale bar is 100 nm. c CD spectra of PEG-PA, PEG-PAO, and PEG-PAS aqueous solutions (0.01 wt.%) at 20 °C. d) CD spectra of aqueous PEG-PAO as a function of concentration at 20 °C. The legends are concentration (wt.%) of polymers in water
