A composition comprising:
- a plasmonic structure including a plasmonic substrate having nanoparticles disposed on the surface of the plasmonic substrate, wherein the nanoparticle is a metal or a biomolecule nanoparticle, wherein a probe is attached to the nanoparticle by a carboxylic acid moiety, wherein the plasmonic substrate is selected from the group consisting of:
- AgFON, Ag nanobowl, CuFON, Cu nanobowl, Cu pyramid, AIFON, Al nanobowl, Al pyramid, and Ag pyramid.
A composition comprising:
- a plasmonic structure including a plasmonic substrate having nanoparticles disposed on the surface of the plasmonic substrate, wherein the nanoparticle is a metal or a biomolecule nanoparticle, wherein the metal nanoparticle is a Cu nanoparticle, Pt nanoparticle, Pd nanoparticle, Fe nanoparticle, Ti nanoparticle, or an oxide of any one of these, wherein the biomolecule is a DNA nanoparticle, RNA nanoparticle, polynucleotide nanoparticle, polypeptide nanoparticle, or protein nanoparticle, wherein a probe is attached to the nanoparticle by a carboxylic acid moiety, wherein the probe is a Raman probe molecule.
A method of forming a hybrid plasmonic structure, comprising:
- exposing a plasmonic substrate to a precursor material;
- irradiating the plasmonic substrate and the precursor material with a light energy;
