Overview of dynamic graphene oxide sorting

Caption

Overview of dynamic graphene oxide sorting: (a) The system uses electron beams on silicon nitride membranes to create electric field patterns that generate opposing forces on graphene oxide sheets. (b) Starting state with graphene oxide sheets in a solution. (c) Middle step showing sheets pulled toward the pattern by electroosmotic flow. (d) Final stage where different-sized sheets move away from the pattern at different speeds due to electrophoretic repulsion forces. Smaller sheets move faster because of their higher surface charge-to-mass ratio.
