Figure 9. Detailed information of π–π stacking interaction between F23 residues and NPs: a). Representative structure of graphene interacting with 4 IAPP22–28 peptides; b) Representative structure of graphene interacting with 8 IAPP22–28 peptides; c) Probability distribution of the average distance between heavy atoms of F23 side chain and NPs.
The heavy atoms of F23 side chain are shown as sticks, and peptides are shown as cartoon.
