Graphene-based filter for isolating a substance from blood

摘要

A device isolates a substance from blood. The substance includes particles with an effective diameter that is within a range defined by effective diameters of constituents of blood. The device comprises a first sheet of graphene including a first plurality of apertures. The first plurality of apertures are configured to pass objects with an effective diameter less than or equal to the effective diameter of the particles of the substance. The device comprises a second sheet of graphene including a second plurality of apertures. The second plurality of apertures are configured to pass objects with an effective diameter less than the effective diameter of the particles of the substance. The device may be configured to include a conduit system. The device may be configured to operate according to a reversible cycle.

1. A method for isolating glucose from blood, the method comprising:
regulating the flow of the blood through a first sheet of graphene and a second sheet of graphene, wherein the first sheet of graphene comprises a first plurality of apertures with an effective diameter that allows passage of glucose across the first sheet of graphene; and wherein the second sheet of graphene comprises a second plurality of apertures with an effective diameter less than the effective diameter of glucose.
