Resumen
The effect of accounting for the total surface in the association of thiol-containing molecules to nanosilver was assessed using isothermal titration calorimetry, along with a new open access algorithm that calculates the total surface area for samples of different polydispersity. Further, we used advanced molecular dynamic calculations to explore the underlying mechanisms for the interaction of the studied molecules in the presence of a nanosilver surface in the form of flat surfaces or as three-dimensional pseudospherical nanostructures. Our data indicate that not only is the total surface area available for binding but also the supramolecular arrangements of the molecules in the near proximity of the nanosilver surface strongly affects the affinity of thiol-containing molecules to nanosilver surfaces.
