(A) Small-angle X-ray scattering data for each PA when dissolved in 10 mM Tris buffer (red), after thermal annealing (black), and after the addition of CaCl2 to thermally annealed solutions (blue). Profile fits (black) are applied for the buffered case only. (B) Cryo-TEM of the same conjugates after thermal annealing (scale bar is 200 nm). (C) Molecular graphics representation of the various peptide amphiphile assemblies. Gadolinium macrocycles are shown in green.
