Abstract
A modified silica material which comprises silica covalently bonded to a synthetic polymer, the synthetic polymer being made from (a) a polymerizable compound capable of being covalently coupled directly to said silica, and (b) one or more polymerizable compounds containing (i) an ionizable chemical group, (ii) a chemical group capable of transformation to an ionizable chemical group, (iii) a chemical group capable of causing the covalent coupling of the compound (b) to an affinity ligand or a biologically active molecule or (iv) a hydrophobic compound.
