The work of Professor Petr Král and his research group on the self-assembly of three-dimensional nanostructures from individual planar graphene sheets (“soggy origami”) has recently been highlighted in the magazine Nature (2009, 462, 658). Petr’s innovative modeling study has found that when water nanodroplets are positioned on graphene sheets they can drive and guide their self-assembly to form more complex structures. Remarkably, water nanodroplets were found to induce induce rapid bending, folding, sliding, rolling, and zipping of the sheets, leading to their self-assembly into sandwiches, capsules, knots, and rings (Nano Lett. 2009, 9, 3766). In a related study with applications in bioelectronics, the Král group has also demonstrated that graphene flakes can be stabilized inside biological membranes (ACS Nano 2010, 4, 229).
