From the background information supplied by the inventors, news correspondents obtained the following quote: "Carbon nanotubes are cylindrical nanostructures containing carbon atoms in a hexagonal arrangement primarily through sp.sup.2 bonds. They can be created by a number of techniques, including chemical vapor deposition, arc discharge, and laser ablation. Carbon nanotubes have generally inert surfaces. Their surfaces may be covalently modified, which may change the electrical and fluorescent properties of the carbon nanotubes."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "In an embodiment of the invention, a fluorescent material includes a medium, carbon nanotubes dispersed in the medium, and a fluorescent surfactant. The fluorescent surfactant is adsorbed to a surface of some of the carbon nanotubes in a concentration sufficient to make the material fluoresce in the presence of radiation.
"In another embodiment of the invention, a method for producing a fluorescent material includes dispersing carbon nanotubes and a fluorescent surfactant in a medium and adsorbing the fluorescent surfactant to a surface of the carbon nanotubes in a concentration sufficient to make the material fluoresce in the presence of radiation
"In another embodiment of the invention, a method for verifying the authenticity of a product having a material includes exposing the material to incident radiation and detecting emissive radiation having a first emission wavelength to verify the authenticity of the product. The material includes a medium, carbon nanotubes dispersed in the medium, and a fluorescent surfactant adsorbed to a quantity of the carbon nanotubes in a concentration sufficient to make the material fluoresce at the emission wavelength in the presence of radiation."
