ABSTRACT:
A method for holding a reactant in a polymer includes combining reactant, hydrogel monomer and a quenching surrogate in a solvent, whereby the solvation of the reactant and the monomer is reduced. The monomer is then polymerized to form a polymer matrix formed around the reactant with sufficient intimacy to replicate the molecular shape of the reactant without chemically attaching to or embedding the reactant. The reactant remains accessible for reaction. More than one reactant may be retained by a polymer matrix. The polymer matrix retaining the reactant is also described. The polymer matrix may be sorbed on a substrate, coated on a substrate, cast into shapes or otherwise made available for reaction.
