摘要:
A device for removal of at least a portion of carbon dioxide from an aqueous fluid includes at least one membrane through which carbon dioxide can pass to be removed from the fluid and immobilized carbonic anhydrase on or in the vicinity of a first surface of the membrane to be contacted with the fluid such that the immobilized carbonic anhydrase comes into contact with the fluid. The first surface exhibits carbonic anhydrase activity of at least 20% of maximum theoretical activity of the first surface of the membrane based on monolayer surface coverage of carbonic anhydrase in the case that the carbonic anhydrase is immobilize on the first surface.
摘要:
A method of modifying cells includes removing fluid including cells from a patient, contacting the removed fluid from the patient with at least one surface upon which at least one agent to interact at least one cell receptor is immobilized to modify cells in the fluid, and returning the fluid to the patient. The agent can, for example, be immobilized via covalent bonding or ionic bonding to the at least one surface. The fluid can, for example, be blood or a blood fraction. The agent can, for example, be an agonist, an antagonist or an inverse agonist.
