Cryocooled thaumatin crystals wrapped in graphene on a Hampton cryoloop. This figure shows two samples of crystals wrapped within graphene, supported in a cryoloop using the graphene as a scaffold. One sample wrapped in three layers of graphene is shown at orthogonal angles in (a) and (b), which illustrate the crystal placement within the cryoloop. (c) shows the crinkling and creasing of five-layer graphene along the contours of another crystal. All three images show the graphene completely covering the thaumatin crystals.
