Residue-specific behavior of GB3 in the presence of 1.2 nM 43 nm AuNPs. (A) A 15N–1H TROSY HSQC spectrum showing selected residues of GB3 in the presence (blue) and absence (red) of AuNPs. No significant chemical shift changes or line broadening is observed. (B) The ratio of peak intensities in the presence versus absence of AuNPs for each residue in GB3. The red dashed line corresponds to the average of all residues, and nearly all residues fall close to this average, suggesting the absence of residue-specific effects.
