Do the two‐step: A two‐step process to make solvent‐free gold nanofluids is reported (see picture). The method comprises the grafting of the thiol MUA onto the gold‐nanoparticle surface, followed by self‐assembly with a PEG‐substituted tertiary amine. The surface functionization adds some novel properties to the nanoparticles, such as conductivity and fluidity.
