Is this a question or a statement? If it is a question the answer is probably yes, otherwise try an amphipathic molecule with cationic character, e.g. C18 dimethyl amine oxide, C18 dimethyl amine or the same of shorther chain length (C16 or C12). Croda used to sell polymeric dispersants for metal particles dispersion, under the trade name of Hypermer or Solsperse. I think they still have on the range.
I did assume that you wanted to make a "dispersion" of nanoparticles and my suggestions of surfactants was make a dispersion of nanoparticles. I agree with the comment in the link you provided, that there are no nanoparticles solutions. But a dispersion of nanoparticles should be close to thermodynamic stability if sufficient surfactant is used.
The real issue with emulsions/dispersions is not so much the kinetic stability. For thes there are effective tools. Much less can be done against Ostwald ripening that is the cause of the thermodnamic instability
