Abstract:
1. A nanostructure comprising: a photocatalytic nanoparticle comprised of a semiconductor material; a first tier of metal nanoparticles said metal selected from the group consisting of gold, silver, and copper, each metal nanoparticle of the first tier being linked about the photocatalytic nanoparticle; and a second tier of metal nanoparticles said metal selected from the group consisting of gold, silver, and copper, each metal nanoparticle of the second tier being linked to one of the metal nanoparticles of the first tier and located a distance from the photocatalytic nanoparticle greater than a distance between a metal nanoparticle of the first tier and the photocatalytic nanoparticle, wherein at least one first linker comprising a condensation product of a linker having an amine fuctional group and a linker having a carboxylic acid functional group is attached to the photocatalytic nanoparticle; a second linker comprising a condensation product of a linker having an amine functional group and a linker having a carboxylic acid functional group is attched to each metal nanoparticle of the first tier; a third linker comprising a condensation product of a linker having an amine functional group and a linker having a carboxylic acid functional group is attached to each metal nanoparticle of the first tier; and a fourth linker comprising a condensation product of a linker having an amine functional group and a linker having a carboxylic acid functional group is attached to second metal nanoparticles of the second tier, wherein like ones of the first through fourth linkers do not attach to one another.
