Abstract
This disclosure relates to graphene derivatives, as well as related devices including graphene derivatives and methods of using graphene derivatives.
Claims24
A material, comprising:
- a graphene derivative comprising a graphene core and a first pendant group, the first pendant group comprising a metal ion and a linking group wherein the metal ion is complexed with the linking group and the linking group is covalenty bonded to the graphene core.
A material, comprising:
- a graphene derivative comprising a graphene core and a first pendant group, the first pendant group comprising a SiO2 nanoparticle covalently bonded to the graphene core through an amide group.
A chromatography column, comprising a column made from metal, glass, or plastic packed with a material comprising a graphene derivative comprising a graphene core and a first pendant group, the first pendant group comprising a metal ion, a nanoparticle, a sulfonate group, an amine group, a quaternary ammonium group, or a chelating group wherein the first pendant group is attached to the graphene core covalenty, or complexed ionically or coordinatively to one or more linking group covalently bonded to the graphene core.
A method of isolating a protein from a sample, comprising:
- disposing the sample in a dispersion comprising a material comprising a graphene derivative comprising a graphene core and a first pendant group, the first pendant group comprising a metal ion, a nanoparticle, a sulfonate group, an amine group, a quaternary ammonium group, a chelating group, or a protein wherein the first pendant group is attached to the graphene core covalenty, or complexed ionically or coordinatively to one or more linking group covalently bonded to the graphene core,
- thereby binding the protein to be isolated to the material to form a protein-bound material;
- isolating the protein-bound material;
- and
- recovering the protein from the protein-bound material.
