Suppression of salt-induced aggregation of 4-mercaptobenzoic acid functionalized gold nanoparticles by aromatic dye molecules

The colloidal instability of ligand-functionalized gold nanoparticles under electrolyte-rich conditions limits their application in plasmonic sensing. Here, 4-mercaptobenzoic acid-functionalized gold nanoparticles (Au–4MBA) were investigated for their aggregation behavior in NaCl-containing media and stabilization by a...
