Abstract
Chemical sensors for detecting analytes in a fluid is disclosed. The chemical sensors include chemically sensitive resistors that utilize carbon nanotubes as a chemically sensitive element. The disclosed sensors additionally utilize polymers which selectively alter or inhibit the chemical sensitivity of the carbon nanotubes. Methods of preparing the sensors as well as methods of their use are also disclosed.
