| membranes, artificial | Artificially produced membranes, such as semipermeable membranes used in artificial kidney dialysis, monomolecular and bimolecular membranes used as models to simulate biological membranes. These membranes are also used in the process of guided tissue regeneration. (12 Dec 1998) |
