Molecule-selective sensor and a process for its preparation

摘要

A molecule-selective sensor has a hollow body (1) in the interior of which are disposed a sensing electrode (4) and a reference electrode (5) immersed in an electrolyte (2). The end of the hollow body (1) is closed by a proteinaceous or other natural membrane (7) which has a surface layer (6) carrying or containing a chemically immobilized enzyme.
