Figure 3

(a,b) Radius of Gyration (RGYR) and Solvent Accessible Surface Area (SASA) plots of the γ-CDPVAHMA at acid (0–50 ns) and neutral-basic pH (51–100 ns), respectively. (c) Number of NFD molecules retained by γ-CDPVAHMA during the three simulations: in methanol (0–50 ns), at acid pH (51–100 ns) and at neutral-basic pH (101–150 ns). (d) Schematic representing the possible interactions between carboxylic groups at acid pH (formation of hydrogen bonds) and hydrogen bonds between deprotonated carboxylic groups and water molecules at neutral-basic pH.
