Amphiphilic polymer 1, 2, or 3 induced changes in lipid bilayers revealed by 31P NMR spectra. Experimental 31P chemical shift spectra of mechanically-aligned bilayer samples of POPC with mole percentages of polymer relative to lipid of (i) 0%, (ii) 1 mol %, (iii) 2 mol %, and (iv) 3 mol %. All NMR experiments were performed with the bilayer normal was set parallel to the external magnetic field of the spectrometer. Other experimental details are given in the main text.
