Abstract
A sensor for detecting analytes of interest is described. Analyte presence or concentration is determined through measurement of changes in induced electromotive force, current or other electrical property in a sensor strip during analyte exposure to the sensor. According to one class of embodiments, the present device immobilizes natural or synthetic macromolecules sufficiently close to an electrically-conductive base member to insure that interaction of analyte with the macromolecules will lead to altered de novo electrical signals in the sensor strip of base member and macromolecules. Performance of the sensor is enhanced by the use of resistance-modifying element in a circuit that includes the sensor strip, and by an adhesive agent disposed between the base member and at least one electrical lead of a detection unit.
