Our simulation shows that these hybrid graphene--membrane superstructures might be prepared by forming hydrated micelles of individual graphene flakes covered by phospholipids, which can be then fused with the membrane. Since the phospholipid layers of the membrane electrically isolate the embedded graphene from the external solution, the composite system might be used in the development of biosensors and bioelectronic materials.

We model the Coulombic, van der Waals and steric interactions between these NPs to understand the exact conditions under ...

The models include van der Waals and Coulombic coupling between nanorods with intrinsic electric dipoles and their coupling to the substrates. We also investigate the effect of external electric fields on the self-assembly processes. Our theoretical predictions for stable self-assembled superlattices agree well with the available experimental data.
