▎ 摘　　要

NOVELTY - Collecting molecules from solution involves providing at least one graphene membrane (212) perforated with apertures selected to allow passage of the solutions' solvent while simultaneously arresting desired molecules upon a surface of the graphene membrane, and dislodging the accumulated desired molecules from the surface for capture and retention. USE - For collecting molecules from solution (claimed) upon the surface of a perforated graphene membrane with apertures. ADVANTAGE - The method can effectively harvest specifically sized molecules and effectively remove them from a surface of a graphene membrane. This is useful where molecules cake and otherwise accumulate in a manner where they cannot be easily dislodged by a simple cross-flow of solution. The vessel and related methodology permits removal of the molecules without having to remove the membranes from the vessel. The unique conductive property of grapheme allows application of the aforementioned electrical dislodging and harvesting device, in a manner not afforded to existing polymer, and hence insulating, membranes in current practice. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for apparatus for selectively harvesting molecules comprising a vessel having an inlet and an outlet, where the inlet receiving a solution and the outlet collecting the solution's solvent, at least one graphene membrane perforated with apertures selected to allow passage of the solution's solvent while simultaneously arresting desired molecules upon a surface of the graphene membrane, and a dislodging device associated with the graphene membrane to dislodge the desired molecules from the surface.
