Fig. 1. 2D 1H–1H NOESY NMR spectra of gold nanoparticles coated by: (top) PEG 1 kDa + PS 2 kDa and dispersed in CHCl3; (bottom) PEG 1 kDa + PNIPAM 1.2 kDa and dispersed in water. Yellow circles indicate positions where cross-peaks corresponding to the chemical shifts of the most intense peak for each polymer would be expected, in case of cross-correlation.
