Abstract
Official abstract text for this publication.
This disclosure relates to graphene derivatives, as well as related devices including graphene derivatives and methods of using graphene derivatives.
First claim
Opening claim text (preview).
What is claimed is: 1. A graphene derivative consisting of graphene oxide and a protein selected from the group consisting of Protein A, Protein G, an E72G3 protein, and their derivatives wherein the protein is covalently bonded to graphene oxide by an amide group and, optionally, a C 1 -C 20 alkylene spacer group. 2. The graphene derivative of claim 1 , wherein the protein is Protein A. 3. The graphene derivative of claim 1 , wherein the protein is a derivative of Protein A. 4. The graphene derivative of claim 3 , wherein the derivative of protein A is His-tagged Protein A. 5. A method of making a graphene derivative consisting of graphene oxide and a protein selected from the group consisting of Protein A, Protein G, an E72G3 protein, and their derivatives wherein the protein is covalently bonded to graphene oxide by an amide group comprising: (1) providing graphene oxide; (2) optionally, activating the carboxyl groups on the graphene oxide; (3) providing a protein selected from the group consisting of Protein A, Protein G, and an E72G3 protein; and (4) reacting the graphene oxide with the primary amine groups on the protein to covalently bind the protein to the graphene core by an amide group. 6. The method of claim 5 , wherein the carboxyl groups on the graphene oxide are activated by N-hydroxysuccinimide and N-ethyl-N′-(3-dimethylaminopropyl)-carbodiimide.
