Graphic depicting how the graphene and crystal are mounted on a Hampton cryoloop. A copper loop supports a droplet of mother liquor solution. Graphene is floated on the bottom of the droplet, and a crystal is dropped in solution onto the hydrated side of the graphene. The cryoloop is then inserted into the droplet below the copper loop (a), oriented horizontally with the crystal situated in the center of the loop, and dragged out through the bottom of the solvent droplet (b). This causes the graphene to wrap around the crystal and the cryoloop.
