    摘要: A biosensor is prepared having a selective detection system containing a biochemical substance such as an enzyme immobilized by reaction with epoxy groups of an olefinic-unsaturated, epoxyfunctional polyether. Prior to immobilization, the polyether is applied to a carrier and crosslinked by treatment with high-energy radiation or peroxide to form a layer. After reacting the biochemical substance with epoxy groups, non-reacted epoxy groups are reacted with a compound containing an amino group and/or a carboxyl group such as an amino acid. Before immobilizing of the biochemical substance and after crosslinking, the polyether may be hydrophilized by reacting some of the epoxy groups with a hydrophilic compound such as an amino acid.
