Metallic nanoshells on porphyrin-stabilized emulsions

DWPI Title: Nanoparticle, has first metallic outer shell and metallic seed shell forming hollow nanoshell surrounding emulsion droplet, and second metallic outer shell provided atop first outer shell
Abstract: Metal nanostructures formed by photocatalytic interfacial synthesis using a porphyrin-stabilized emulsion template and the method for making the nanostructures. Catalyst-seeded emulsion droplets are employed as templates for hollow-nanoshell growth. The hollow metal nanospheres may be formed with or without inclusions of other materials.
Use: Nanoparticle.
Advantage: The photocatalytic reduction of metal ions produces a surface distribution of catalytic metal seed particles to autocatalytically or photocatalytically promote growth of a metallic sphere at the surface.
Novelty: The nanoparticle has a metallic seed shell whose diameter is approximately equal to or greater than a diameter of an emulsion droplet and surrounding the emulsion droplet. A hydrophobic substituent of lipoporphyrin molecules is contained within a surface region of the emulsion droplet. A metallic outer shell is provided atop the seed shell. The shells form a hollow nanoshell surrounding the emulsion droplet. A second metallic outer shell is provided atop the former outer shell. A metallic composition of the latter outer shell is not identical to that of the former outer shell.
