Argonne National Laboratory physical chemist mixes a polyethylene glycol (PEG) coating for synthesized polymer nanospheres as polymer chemist examines a different PEG formulation.
The coated nanosphere can be injected into humans following exposure to chemical, biological, or radiological toxins. The nanospheres selectively pick up these toxins and they are drawn out through a magnetic filtration system outside the body. The technology shows promise for delivering therapeutic drugs to target cells and organs. It is designed to directly remove the toxic agents from the bloodstream quickly and efficiently. Some potential applications are: biological toxin exposure, radiological toxin exposure and radioprotection, internal hemorrhage, brain swelling, stroke therapy, cancer therapy and acute trauma leading to kidney failure. The technology uses components approved by the U.S. Food and Drug Administration and a novel approach to magnetic filtration. This joint project by ANL, Armed Forces Radiobiology Research Institute and the University of Chicago hospitals.
