IDEA #4IDSL8 Enzymatic Graphene-peptide Dispersion 24A0003.

This invention uses biocompatible materials and eliminates the restacking and aggregation tendency that graphene has in water. surface functionalization techniques with biomaterials such as peptides and proteins have yet to be further explored. Through this biofunctionalization method, an array of possibilities emerge, where different peptides sequences containing tyrosine can finely tune and modify the functionality of graphene, enabling the integration into a toxic free and biocompatible range of applications. The reproducibility and simplicity of this process allows to produce pre-functionalized graphene products that are dispersible in water, possibly competing with commonly utilized graphene analogues such as graphene oxide GO or reduced graphene oxide r-GO. In theory, given the diversity of function that arise from different peptide sequences, covalent modification using this methodology would allow for one to adjust the residues used based on application needs.
