The present invention relates in general to the preparation and use of matrices having solid spaces, interstitial spaces and interstitial polymer networks. In particular, the interstitial polymer networks have utility in chemical and biochemical separations, solid phase synthesis, catalysis of chemical reactions, and immobilized enzyme reactors. The interstitial polymer networks in one embodiment comprise crosslinked polymers suspended in the interstitial spaces from and/or between solid particles. The matrices are characterized by high ligand and functional group density and by reversible high sorptive and binding capacity, and are substantially accompanied by a very low nonspecific adsorption or interaction with molecules such as proteins. Moreover, the matrices of the invention exhibit other characteristics highly desirable in chromatographic and catalytic applications, such as high physical rigidity, high ligand density, chemical stability, high ligand reactivity, and rapid exchange and reaction kinetics.
A matrix comprising solid particles and interstitial space comprising (a) a cross-linked interstitial polymer network covalently attached to said particles which forms an integrated contiguous network in said interstitial space that is permeable to liquids, is effectively a large pore polymer contained within the interstitial space of the matrix and is sufficiently thin or dilute so as to not act as a significant barrier to fluid flow, and (b) a member of a binding pair, wherein at least one of the monomers used to synthesize said network comprises a hydrophilic monomer and wherein said solid particles have an irregular shape.
