Synthesis of gold nanoparticle surfactants and their self-assembly at oil-water interfaces

Creator:: Truong, Mitchell
Abstract:: Amphiphilic gold nanoparticle surfactants can self-assemble at oil-water interfaces to form stable Pickering emulsions. These nanoparticle surfactants have previously been synthesized by functionalizing gold nanoparticles with thiol terminated polyethylene glycol (PEG-thiol), and subsequently with an alkane-thiol. It is necessary to improve the bio-compatibility of the nanoparticles if they are to...
