Graphene has potential applications in a variety of fields including electronics, photonics and chemical-biosensing. In this study, we perform molecular dynamics (MD) simulations to study the interactions between graphene sheets and biomolecules. The bending behavior of graphene induced by adsorption of peptides is investigated. The influence of peptide size, number, and alignment on the deflection of graphene sheets is studied in detail. The van der Waals (VDW) interaction plays a dominant role in the interaction between peptides and graphene. Our study provides valuable information for the experimental design of nanodevices incorporating graphene with biomolecules.
