A multipurpose and transferrable sample platform for supporting, analyzing and/or processing a target material. The platform includes a substrate; a dielectric layer formed over a face of the substrate; electrodes formed over the dielectric layer; a slot formed through the substrate and the dielectric layer; and an exfoliated graphene-based membrane placed over the slot and in electrical contact with the electrodes. The exfoliated graphene-based membrane is configured to support, or act upon, a study material or chemical precursors.
