CHEMICAL SENSORS EMPLOYING CATALYTIC ANTIBODIES

摘要

A sensor for the analysis of physical and chemical changes in a test solution includes a glass tube (10) with an end covered by a membrane. The glass tube contains an internal Ag/AgCl electrode (24) in solution (22). The membrane (14) is a dialysis membrane which allows ions to pass through and contact an antibody immobilized on a spacer material (12). This spacer material (12) is placed between the dialysis membrane (14) and a glass membrane (16), thereby forming a sensing area (18).
