Abstract

Methods and assemblies for the construction of liquid-phase alloy nanoparticles are presented. Particle formation is directed by molecular self-assembly and assisted by sonication. In some embodiments, eutectic gallium-indium (EGaIn) nanoparticles are formed. In these embodiments, the bulk liquid alloy is ultrasonically dispersed, fast thiolate self-assembly at the EGaIn interface protects the material against oxidation. The assembly shell has been designed to include intermolecular hydrogen bonds, which induce surface strain, assisting in cleavage of the alloy particles to the nanoscale. X-ray diffraction and TEM analyses reveal that the nanoscale particles are in an amorphous or liquid phase, with no observed faceting.
