Abstract: The present invention relates to a sensor for analyte detection. The sensor makes use of changes in electrostatic fields associated with macromolecular binding agents during their interaction with analytes. Specifically, analyte presence leads to increases in magnetic flux generated by the motions of the binding agent electrostatic material. Magnetic or induced electrical signals may be monitored for change in order to detect analyte in a sample of interest.

Abstract: A sensor for detecting analytes is described. Analyte presence or concentration is determined through measurement of changes in induced electromotive force, current or other electrical property in a base member 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 any alteration in the motion and/or electrostatic fields of the macromolecules during interaction with a predetermined analyte will induce an increased electromotive force in the base member.
