Abstract 摘要 |
First, we demonstrate by molecular dynamics simulations that water nanodroplets can activate and guide folding of planar graphene nanostructures. Nanodroplets can induce rapid bending, folding, sliding, rolling, and zipping of graphene nanostructures, which can lead to their self-assembly into sandwiches, capsules, knots, and rings [1]. Next, we show that graphene ribbons can wrap in complex but controllable ways on the surfaces of nanostructures and in their interiors [2]. We continue by discussing our coarse-grained molecular dynamics simulations of graphene sheet insertion in the hydrophobic interior of biological membranes formed by amphiphilic phospholipid molecules [3]. The formed superstructures should allow building of novel bio-electronic systems. Finally, we model the self-assembly of nanoparticle monolayers inside biological membranes [4], and describe also self-supporting nanoparticle membranes observed in recent experiments. [1] N.
