a) Structural features and relative sizes of amino acid-functionalized gold nanoparticles and proteins. The blue overlapping spheres in the proteins represent the positively charged residues on their surface. b) Plots of entropy (TΔS) versus enthalpy (ΔH) for NP-protein (number of data set n = 23) interactions. c) Slope (α) and intercept (TΔS0) values for various host-guest systems. Protein-ligand interactions have been divided into protein-peptide and protein-other (protein-ligand) interactions.
