Diffusion coefficients of compounds in various media. (A) In four PBS-based media; (B) In four D2O-based media. The pH of each medium was 7.4. ◆, H2O; ■, 1; ●, 2; ★, 3; ▼, 4. Solid symbols: in PBS media; hollow symbols: in D2O media. Standard deviation of D(H2O) in solvent is 0.08 × 10−10 m2s−1, based on 4 repeated measurements.
