Molecular recognition sensor system
First Claim
1. A molecular recognition sensor system comprising:
- a resistive sensor including a semiconductive polymer film which swells when exposed to an analyte and interferents;
a molecular imprinted resistive sensor including a semiconductive polymer film imprinted with the analyte to produce cavities therein, in which the film thereby swells when exposed to interferents but not analytes when said analytes are at a concentration less than or about equal to a concentration of the cavities; and
a circuit connected to the resistive sensor and the molecular imprinted resistive sensor for detecting a change in the resistance of the resistive sensor when exposed to the analyte and the interferents, the change in the resistance of the molecular imprinted resistive sensor when exposed to the analyte and interferents, and for subtracting the change in resistance of the molecular imprinted resistive sensor from the change in resistance of the resistive sensor to reduce the effect of any interferents on the change in resistance of the resistive sensor thereby determining the presence and concentration of the analyte.
