Abstract:
1. A nanoparticle comprising: an emulsion droplet; a plurality of lipoporphyrin molecules, wherein a hydrophobic substituent of the lipoporphyrin molecule is contained within a surface region of the emulsion droplet; a metallic seed shell of diameter approximately equal to or greater than a diameter of the emulsion droplet and substantially surrounding the emulsion droplet; a metallic outer shell atop the metallic seed shell, wherein the metallic seed shell and the metallic outer shell form a hollow nanoshell surrounding the emulsion droplet; and a second metallic outer shell atop the metallic outer shell, wherein the metallic outer shell has a first metallic composition and the second metallic outer shell has a second metallic composition that is not identical to the first metallic composition.
