Fig. 4From: Thermosensitive core-rigid micelles of monomethoxy poly(ethylene glycol)-deoxy cholic acida1H-NMR spectra of mPEG350-DC in CDCl3 and D2O at 15 °C. Compared with the PEG peaks at 3.0–4.5 ppm, the DC peaks at 0.5–2.5 ppm are collapsed in D2O. b TEM images of mPEG350-DC developed from aqueous solution (1.0 wt.%).
