Patent ID: 7998368

Claim:
A method of dispersing carbon nanotubes (CNTs) in a solution, comprising the steps of: creating an aqueous buffer solution consisting of at least 50 weight percent water and a remainder weight percent that includes a buffer material having a molecular structure defined by a first end, a second end, and a middle disposed between said first end and said second end, said first end defined by a cyclic ring with nitrogen and oxygen heteroatoms, said middle defined by a hydrophobic alkyl chain at least approximately 0.45 nanometers in length, and said second end defined by a charged group; mixing CNTs in said aqueous buffer solution in a ratio of up to approximately 1.0 milligrams of CNTs per 1.0 milliliter of said aqueous buffer solution wherein a resulting solution includes said CNTs dispersed therein; and mixing metal-core cationized ferritins into said resulting solution.
