Selectively permeable membrane, process for the production thereof and their use in the case of an electrode.

摘要

An electrode comprising an electrically conductive base, and a selectively permeable membrane which is produced by forming a membrane from a mixed solution comprising (a) albumin, (b) at least one type of crosslinking agent and (c) chitosan. The selectively permeable membrane is useful, e.g., in conjuction with an electrode. An enzyme electrode is also provided having the selectively permeable membrane disposed on the electrode and an immobilized enzyme membrane disposed on the selectively permeable membrane. The immobilized enzyme membrane is prepared by incorporating a carboxylate into the solution containing the enzyme and an aldehyde as the crosslinking agent. The crosslinking is effected by heating or drying.
