    摘要： A method of forming a nanoparticle can include admixing an aqueous solution into an oil-phase to thereby form an emulsion of droplets of the aqueous solution in the oil phase, the aqueous solution comprising a nanostructure precursor and a polymer, adding a silane precursor and catalyst to form a silica shell around each of the droplets to nanoreactors; annealing at a first temperature below the decomposition temperature of the polymer to aggregate the nanostructure precursor within the nanoreactor; and annealing at a second temperature above the decomposition temperature of the polymer to convert the aggregated nanostructure precursor to the nanostructure and decompose the polymer.

    摘要： A protein template dispersion solution of the present embodiment includes a protein template containing two or more types of heterogeneous metal ions or alloy nanoparticles; and a solvent in which the protein template is dispersed, wherein alloy nanoparticles are obtained by removing the protein template. A method of producing a protein template dispersion solution according to the present embodiment includes: a step in which a protein template is added to a solution in which heterogeneous metal ions are dissolved and metal ions are introduced into the protein template; and a step in which the protein template and metal ions that are not incorporated into the protein template are separated. A method of producing alloy nanoparticles according to the present embodiment includes a step in which a dispersion solution of heterogeneous metal-ion-containing protein templates is subjected to a heat treatment under a reducing atmosphere to remove a protein template.
