Abstract

A method of making a multilayer metal particle having an irregular surface architecture includes introducing a molten eutectic metal alloy into a solution to produce a eutectic-solvent mixture, shearing the eutectic-solvent mixture for a sufficient period of time to induce surface tension driven phase segregation in the molten eutectic metal alloy to produce an irregular surface architecture on the eutectic metal alloy, allowing the molten eutectic metal alloy to precipitate to produce a plurality of particles, allowing the plurality of particles to oxidize in the presence of an oxidizer, and functionalizing the particles with an organic species to form an organic layer to produce a multilayer metal particle having an irregular surface architecture.
