| 摘要 |
A method and apparatus for removing and/or modifying specific target substances in the blood is disclosed. The invention includes a column or chamber in which selected bioreactant molecules are suitably retained for reaction within a porous hydrogel polymer matrix by reversibly quenching the reactant propensity with a displaceable surrogate and polymerizing an insoluble cross-linked hydrogel in such manner that the hydrogel polymer replicates the shape of the bioreactant molecule. This replicated phantom shape in the polymer then exhibits profound dispersion-force affinity for the bioreactant. The invention provides for retention of a wide variety of therapeutic reactants and reaction products while confining the reaction within the column.
