    • For NPs prepared without any additional salt, the number of ions in solution is directly equal to the number of charged ligands adsorbed on the NPs surface. Here, the ratio between the number of ions and the number of metal atoms is Nions/Nmetal = 3v/(aRc), where a = 21.4 A2 is the adsorption area of the ligands,25 v 17 A3 is the molar volume of bulk Au or Ag, and Rc = 3 nm is the radius of the NP's metal core.
