Graphene oxide for bioconjugation

Our bioconjugatable graphene oxide brings the advantages of two-dimensional materials to biotechnology. The fluorescence quenching property of graphene oxide has been used in many biosensor applications. Amine functionalization makes our graphene oxide easy to couple your protein, antibody, or other carboxylic acid containing target for use in biosensor applications based on fluorescence quenching. Additionally, graphene oxide has been used extensively in tissue engineering applications. PEG modification may even increase the biocompatibility of graphene oxide in vivo. Lastly, graphene oxide has been used in targeted drug delivery and in photothermal cancer therapy, and our bioconjugatable graphene oxide makes it easier to add your targeting ligands.

Graphene oxide is a hydrophilic two-dimensional (2D) material that is dispersible in water. This graphene oxide product contains covalently bound 6-arm PEG (15K) amine linkers that can be used for bioconjugation with carboxylic acid containing biomolecules. The 6-arm PEG amine functionality increases the number of binding sites for bioconjugation versus graphene oxide, and the amine groups offer popular and established coupling chemistry.
