Phosphazene polymer carrier for biologically active substance.

摘要

A biologically active substance-immobilized carrier comprising phosphazene polymer having side chains, characterized in that among side chains of the phosphazene polymer present in at least a surface layer portion of the carrier, the biologically active substance has been immobilized to at least a portion of the side chains and a remaining portion of the side chains substantially consist of organic radicals which are non-reactive and hydrophilic; and a carrier for immobilizing a biologically active substance which carrier comprises phosphazene polymer having side chains, characterized in that side chains of the phosphazene polymer present in at least a surface layer portion of the carrier substantially consist of organic radicals having a functional group capable of bringing the biologically active substance and of organic radicals which are non-reactive and hydrophilic.
