Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
88 words
A variable resistance sensor for the determination of an analyte in a medium, comprising a) an insulating structure (14, 114) b) element means (10, 110) having an active part comprised of semiconductive organic polymer including a specific binding substance for the analyte, mounted on said structure (14, 114) for exposure to the medium (12, 112) and c) electrodes position to contact the element (10,110) characterized in 'that said semiconductive organic polymer is selected from the group consisting of polyacetylene, poly(p-phenylene), polypyrrole, polyalkadiynes, poly(p-phenylene sulfides), polymetallophthalocyanines and polyphthalocyanine siloxane.
Claim 2
Dependent Claim
88 words
A variable resistance sensor for the determination of an analyte in a medium, comprising a) an insulating structure (14, 114) b) element means (10, 110) having an active part comprised of semiconductive organic polymer including a specific binding substance for the analyte, mounted on said structure (14, 114) for exposure to the medium (12, 112) and c) electrodes position to contact the element (10,110) characterized in 'that said semiconductive organic polymer is selected from the group consisting of polyacetylene, poly(p-phenylene), polypyrrole, polyalkadiynes, poly(p-phenylene sulfides), polymetallophthalocyanines and polyphthalocyanine siloxane.
Claim 3
Dependent Claim
