Abstract:
1. A sensor for sensing the presence of an analyte component, the sensor comprising: a plurality of conductive polymer strands each having at least a first end and a second end, and being in contact with a molecular insulator that isolates one or more of said conductive polymer stands from one or more other conductive polymer strands on the sensor; a plurality of molecular recognition headgroups having an affinity for said analyte component and being attached to said conductive polymer strands such that when the analyte interacts with the molecular recognition headgroup one or more mobile charge carriers are transferred to a conductive polymer strand attached to said headgroup; and an electrode substrate attached to said conductive polymer strands at said second ends configured to report to an electronic circuit reception of mobile charge carriers from said conductive polymer strands whereby the presence of said analyte component is sensed.
