Proton nuclear magnetic resonance (1H-NMR, 500 MHz) spectra. D2O was used as NMR solvent for HA, HA-PEG-DMPE, HA-PEG-DSPE, and HA-PEG-Chol. CDCl3 was used as NMR solvent for DMPE-PEG-NH2, DSPE-PEG-NH2, and Chol-PEG-NH2. The degree of Lipid-PEG-NH2 conjugation in HA backbone was calculated by peak integration between the N-acetyl group of HA (δ1.9 ppm) versus the terminal –CH3 of lipids (δ0.8–0.95 ppm). Red box indicates the degree of lipid substitution
