Patent Title: Capture and removal of biomolecules from body fluids using partial molecular imprints
Publication date: 2006
Publication number: US2006030027

Abstract: The invention provides methods and devices for the capture and removal of target biomolecules from a patient's body fluid, particularly blood or a blood component, using a partial imprint material. The partial imprint material is composed of a matrix composition having partial imprint cavities that correspond to a segment of a target biomolecule but which are capable of removing the entire target biomolecule from the body fluid. The method can be implemented by removing a volume of a patient's body fluid, e.g., blood, bringing the body fluid or a component thereof into contact with the partial imprint material under conditions effective to capture the target biomolecule, and returning the body fluid to the patient. A modified dialysis or apheresis device can be used in which the body fluid is removed, continuously passed through a circuit containing the partial imprint material, and re-introduced into the patient's body following treatment.
