1. A sensor for detecting an analyte, comprising:
- a base member having a conductive property, said base member defining a first conductive element;
a binding agent layer proximate said base member;
a semiconductive element proximate said base member; and
, a second conductive element that is electrically contacted to said semiconductive element and said first conductive element;
wherein said base member and said binding agent layer define a sensor strip.

Abstract
A sensor (700) for detecting analytes of interest in which natural or synthetic macromolecules (740) are immobilized on an electrically conductive base member (720) to insure that interaction of analyte with the macromolecules will lead to altered de novo electrical signals in a sensor circuit (720,770,198).

10. A method for detecting a predetermined analyte, comprising the steps of:
-
providing an electrically conductive base member, said base member defining a first conductive element;
forming a binding agent layer of macromolecules in proximity to said base member, wherein said macromolecules are capable of interacting at a level of specificity with said predetermined analyte, disposing a semiconductive element proximate said base member, wherein said base member, said binding agent layer and said semiconductive element define a sensor strip;
exposing said predetermined analyte to said binding agent layer, and, detecting an electrical current generated in a closed electrical circuit, said electrical current being responsive to a presence of said predetermined analyte, wherein said closed electrical circuit comprises said base member, said semiconductive element, and a second conductive element electrically contacted to said semiconductive element. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
