20130248367, Sep 26, 2013

Filed:

Mar 14, 2013

Appl. No.:

13/804085

Inventors:

SARAH SIMON - Baltimore MD, US

Assignee:

LOCKHEED MARTIN CORPORATION - BETHESDA MD

International Classification:

B01D 61/42

US Classification:

204518, 204627

Abstract:

A molecular separation device includes a chamber having an inlet and an outlet through which flows an aqueous suspension and a porous separation membrane positioned in the chamber substantially orthogonally to the flow of the aqueous suspension. An electrical charging device connects to the separation membrane to apply a periodic electric charge so as to collect components blocked by the porous separation membrane. Related methods are also disclosed.

Abstract:

Some embodiments comprise membranes comprising a first layer comprising a porous graphene-based material; a second layer comprising a porous graphene-based material; a channel positioned between the first layer and the second layer, wherein the channel has a tunable channel diameter; and at least one spacer substance positioned in the channel, wherein the spacer substance is responsive to the environmental stimulus. In some cases, the membranes have more than two layers of porous graphene-based material. Permeability of a membrane can be altered by exposing the membrane to an environmental stimulus. Membranes can be used in methods of water filtration, immune-isolation, timed drug release (e.g., sustained or delayed release), hemodialysis, or hemofiltration.

International Classification:

A61M 1/16

Abstract:

Perforated graphene and other perforated two-dimensional materials can be used in hemodialysis membranes and blood filtration membranes for selective removal of components from blood in vivo and ex vivo. The membranes are useful in hemodialysis and hemofiltration techniques to provide improved patient care. Hemodialysis systems can include a hemodialysis membrane formed from perforated graphene or another perforated two-dimensional material disposed upon a porous support structure. Hemofiltration systems can include one or more and preferably two or more blood filtration membrane formed from perforated graphene or another perforated two-dimensional material disposed upon a porous support structure. Methods for performing hemodialysis can involve exposing blood from a patient to a hemodialysis membrane formed from a perforated two-dimensional material. Ex vivo dialysis techniques can be performed similarly. Methods for filtration of blood can involve passing blood through one or more filter membranes or through a plurality of sequential filter membranes.
