Claims9
A variable resistance sensor for the determination of an analyte in a medium comprising:
- (a) an insulating structure,
- (b) element means having an active part comprised of semiconductive organic polymer of polyacetylene including a specific binding substance for the analyte, mounted on said structure for exposure to the medium and
- (c) electrodes positioned to contact the element.
A method of identifying the type and quantity of an analyte in a medium comprising the steps of:
- (a) preparing an element of semiconductive organic polymer of polyacetylene
- (b) treating the element with a specific binding substance,
- (c) exposing the element to the medium,
- (d) measuring the change in an electrical characteristic of the treated element.
