Abstract
A sensor includes a substrate, a first electrode, a second electrode spaced from the first electrode, and a sensing medium on the substrate between the first electrode and the second electrode. The sensor medium includes a functionalized graphitic material and an uncondensed graphitic carbon nitride disposed upon the functionalized graphitic material. The sensor further includes a system for applying electromagnetic energy to the sensing medium to increase the conductance of the sensing medium, and circuitry including at least one measurement system in operative connection with the sensor to measure a variable relatable to the conductance of the sensing medium which is dependent upon the presence of an analyte to be detected.
