      abstract     = {Graphene and its derivatives, such as graphene oxide (GO)
                      and reduced graphene oxide (rGO), havepropelled advancements
                      in biosensor research owing to their unique physicochemical
                      and electroniccharacteristics. To ensure their safe and
                      effective utilization in biological environments, it is
                      crucial tounderstand how these graphene-based nanomaterials
                      (GNMs) interact with a biological milieu. Thepresent study
                      depicts GNM-induced structural changes in a self-assembled
                      phospholipid monolayerformed at an air–water interface
                      that can be considered to represent one of the leaflets of a
                      cellularmembrane. Surface pressure–area isotherm and
                      electrostatic surface potential measurements, alongwith
                      advanced X-ray scattering techniques, have been utilized in
                      this study. Experimental findingsdemonstrate a strong
                      interaction between negatively charged GO flakes and a
                      positively chargedmonolayer, primarily dictated by
                      electrostatic forces. These GO flakes assemble horizontally
                      beneath thehead groups of the monolayer. In contrast, rGO
                      flakes permeate the zwitterionic lipid layer throughdominant
                      hydrophobic interaction. This organization of GNMs alters
                      the in-plane elasticity of the lipidfilm, exhibiting a drop
                      in the electrostatic potential of the surface according to
                      the extent of oxygencontaininggroups. These results provide
                      a solid groundwork for designing devices and sensors aimed
                      ataugmenting the biomedical applications of GNMs.},
