The analysis of hydrogen bonds (H-bonds) and ionic contacts of the AuNP terminal groups and solution was carried out by averaging over five time windows using five snapshots of the total trajectory as starting structures for 1 ns simulations with a data storage rate of 1/(0.5) ps. Contacts between the AuNP terminal groups and water molecules were considered within a cutoff distance of 0.35 nm for non-hydrogen atoms and a H-bond angle of 30°. Ion contact analysis of the AuNP solutions was performed considering ions within a cutoff distance of 0.35 nm from AuNP terminal groups.
