Insight into the Interactions of Amyloid β‐Sheets with Graphene Flakes: Scrutinizing the Role of Aromatic Residues in Amyloids that Interact with Graphene Academic Article uri icon


  • The interaction of amyloid β-sheet segments with graphene-flake models is investigated by using DFT calculations. The structure of β-sheets of selected amyloid segments is based on crystal structures obtained from the Protein Data Bank. Our study, based on DFT calculations for model systems, indicates that the interaction in amyloid-graphene aggregates can be stronger than the interaction in the respective amyloid-amyloid aggregates. The results also indicate an important specific role of aromatic sidechains in amyloid-graphene interactions. This work confirms recent experimental evidence that graphene and its modifications inhibit the aggregation of β-amyloid peptides.
